Decriminalization of drugs would be a big step to gutting violence.
The war on drugs hasn't stopped addiction. Drugs is a religious and moral issue. I'm not saying it wasn't well intended, but it has grossly backfired from the start, just as Prohibition did. Street violence happens for three reasons a vast majority of the time, drugs, money or relationship emotions (don't read that as just romantic relationships), and those are targeted crimes. We might think some murder is random, but the news rarely follows up on the details of a case unless it's big event.
Thefts, especially on the street, are certainly random, so my head is always on a swivel, but I don't walk around downtown Indy ever thinking my safety is in danger. I'm in downtown Indy a lot.
Show me the communities that actually spent less money on police? You'll find most police budgets raised, inserting more community based stations and utilizing more outreach.
Any issues with youth accountability, I point back to no longer having community public schools in urban areas. With no connection to where they live for a large number of kids, it leads to them not caring. It leads to them being strangers in their community. Less familiarity, less accountability.
When was the last time you were in an urban school? I'm in them often. Lots of talk about kids having issues getting to school. Those are mostly athletes that come across my ears, but speaking from experience, since I took in a kid for 14 months, often times the other aspects of school are the only reason why some choose to follow through on school.
School choice has crushed urban public school systems.
I don't know what the laws in your state are, but you can't have stop and frisk in a state that has permit less carry laws.
