Lmao, the American delusion.
1. So what? The USA has ~300M people, but Mexico has ~100M and Brazil ~200M. Do you see Mexico and Brazil having 1/3 (83 shootings) or 2/3 (166 shootings) of your shootings? No, right? So this point is moot.
Oh, but you're not satisfied with population? Sure, let's look at surface. The USA has ~9.8M km², but Brazil has ~8.5M km² and Mexico has ~1.9M km²1. Do you see Mexico and Brazil having 1/5 (50 shootings) or 4/5 (200 shootings) of your shootings? No, right? So this point is moot.
2. Sorry... What? Are you actually delusional? How can you even attempt to say that? The laxest border you have is the USA-Canadian border, and there officers pester you about what you're doing there, what are your intentions, for how long you're planning on staying etc. Don't get me started with the USA-Mexico border, you literally got ICE, walls and the camps. Do you not watch the TV????? How can you say anyone can cross the border?????
And, on top of that, freely crossing the border has shown to NOT matter, actually. You know in Europe you can cross almost ANY border without being asked a SINGLE question, right? Try to cross from Spain to France, from the Netherlands to Germany, from Ireland to the UK and you'll barely notice you just got in another country (you only notice because there's normally a sign saying "Welcome to X"). So, yeah, this point is also moot.
3. Sure, your policemen suck at their job. But, the thing is, many of those 249 shootings (sorry, 250 now) has been perpetuated by people without any type of criminal background, people that were not deemed "dangerous", but that got a gun and decided to use it for its only intended purpose (to kill). So yeah, the FBI should totally do a better job at taking care of the people they know are dangerous. But if you've repeatedly had lots of trouble with people that weren't supposed to be dangerous, is it not time to try a new approach? Shouldn't you at least DO something different, if what you're doing now isn't working?
4. Sorry but what? A lot of these shootings are perpetuated by your """""Normal, Typical, Very Much Not Criminal, White Man"""". That you think that the core of the problem is gang violence is preposterous and probably rooted in racism. But EVEN if the majority of these shootings were because of gang violence, the point still wouldn't be in that. Yes, shootings between different gang groups is horrible and should be stopped, and, yes, many innocent people can be shot - and killed - in a gang shoot-out. But do people actually talk about these shootings? Do you really think people moan about gang shootings? Of course not, people complain about how one person (who 90% is not in or in any way related to any type of "gang group" or "inner city smug" or whichever euphemist way you want to take to say "scary black guy) goes to a random public place (school, high school, mall, concert, even garlic festival, you can choose whatever place you want and chances are there will have been a shooting there) and decides to mow down as much people as he (or she, but let's be honest the majority are a he) can. So tell me again how the mass shooting problem has to do with gang violence. Tell me again how a man showing up to a high school and promptly killing as much people has he can has to do with gang groups. Tell me about it, because I'm honestly curious how one could even attempt to link the two.
And, yes, the list could go on, especially the least could go on and on reasons why you need to do something different, the reason goes on and on on why you need to stop sending meaningless thoughts and prayers to dead people. A thought will not stop a killer, a prayer will nit dislodge a bullet in a victim's head. Only actions will, PREVENTIVE actions. And, look dude, I'm not saying you should take away all of the second amendment (even if I personally think it's only not a dumb amendment right now, but also grossly misinterpreted from its original meaning), I know historical traditions will most ofently trump apparent logical decisions. What I'm asking y'all to do is ACT. Get harsher background checks, actually ask people to prove they can and know how to use a weapon, make them pass regular exams, make it so if someone WANTS to have a weapon, they have to REGULARLY prove that not only are they sane (both physically and mentally) but also know everything they have to know about them (make them attend regular shooting trainings and exams, be sure they know how to properly take care of their firearms, get inspections to their homes so they can actually prove they'll be storing their gun and bullets SAFELY and SEPARATELY, etc). Also get harsher laws about gun carrying.
Why should someone be allowed to open carry a gun in the middle of the street? There's literally no reason. And before someone comes and tells me that this way they feel secure from "gang violence", just know that A: that's simply not statistically true and, B: that's the police job, not yours.
Why should automatic and semi-automatic guns be allowed? (In the sense of the big guns capable of firing multiple shots per second). How many bullets per second do you actually need to defend your home? A handgun is more than enough. If you want to go hunting, a hunting gun is more than enough, you don't need to fill anyone, or anything, with 60 bullets in under a minute. And, yes, I know some people like to have those guns to go to a shooting range but, is it honestly worth it? Should we really allow literal killing machines (because the other guns you could argue that they have other slightly different better purposes, like defending yourself or go hunting) to roam the cities? Should we let people get basically-militar weaponry just so that a couple of dudes can feel good about themselves by filling a paper with bullets?
tl;dr: Just PLEASE stop thinking and praying and actually start DOING.
