@roger,
It has nothing to do with immigration.
2001 came and nobody wanted war but before that let me tell you a bit of what our violence problems were in my area.
1. Gangs. Wanna-be asking for money, to forcing people in their pre-teens for their money. I could not wake up and not hear bs.
2. Not prostitution but the fact the 1990's was positive in terms of sexuality.
What changed after 2001 was anti-privacy abusing the patriot act and attacking heterosexual peoples to creating more jail time for something that was natural.
3. Rap music and the mentality that came with it. Along with discrimination. In my opinion was a complete out right racist joke where just by having a light skin complexion, being some what dedicated to studies, you was a target. The amount of pregnant girls that otherwise could lead normal lives. So far a majority of shooters all rotate around negativity towards rap music.
4. The lack of peace. In the 1990's we had a movement for peace. After 2001 it was nothing but propaganda against these imaginary terrorists and discrimination for almost anybody who look like Islamic stereotype.
5. Obama being elected was not really that great the problem was his stance on LGBT. That being said nobody care about the war and people just elected Trump out of that one fact. It was back to "Oh it was for the taxes"
6. Trump stance on immigration was about not honoring the POW rights. POW who have been on US soil ( this includes embassy ) are allowed the right to have citizenship in the US. These camps ( as with WWII Japanese camps ) basically instead of inviting them ( like the Germans was invited ), they wanted to ship them back. Tons of people from Iraq, Afghanistan, and other nations have since moved to the United States.
7. Hillary talk about "Super predators" meant to actually attack men but especially men who are not European ( white enough ). That being said back in the Clinton Administration was setting up for the anti-privacy along with the right to run privately own prisons ( where much illegal activity is carried out ).
.......
Point being nobody is trying to cure the problem ( method of thinking ) because USA wants that thinking for Military people. Thus producing-mass amounts of idealize infantry, and other types in the military.
.........
That hospital shooting was justified. That man was ignored by his doctor. He is afraid of his health and the medical doctor/physician was ignoring him like some kind of movie star.
If the doctor said "please come in we will check you out" maybe those lives would have been saved. For all we know he hang the phone up in his face ( most likely the secretary ), or was not taking his plead for help serious enough. So they guy believed he was having internal bleeding.
