I moved to Texas in '05 to raise kids.
I got tired of syringes in the playground, and constant threat and danger everywhere we went.
With the tax savings and lower house prices, we were able to buy a great house near a lake, with good schools and a safe, walkable town.
It was a huge leap for us, but one of the best choices I ever made.
What did you find odd about that? That a European doesn't want to live in a dangerous city?
That is the distinction you've seemed to miss here.
Controlling others' behavior is ineffective at best. It's treating symptoms with pain killers while ignoring the source of the problem. It's weak leadership, and, it gives broken people the ability to manipulate the system to hurt others.
All the non federal governments can do is like removing bus stops (or letting drug addicted communities flourish when the pendulum swings the other way).
The solution is canvassing, campaigning, voting, and running for federal office where that change can be affected.
I just met an Uber driver from Germany the other day. He lives in Georgia (the state) now and was talking about how he moved to this town to get away from the dangerous city nearby. He was happy that his kid could ride around on his bike like back home in his village in Germany. I remember thinking it odd because I had never heard a European talk like that. But I suspect they don’t “get it” until they actually live it.
