That’s pretty much in line with the ability of the police to prevent crime. They can’t. They only clean up the mess afterwards.
That’s not really true. I’ve seen what a good LT with about 15 officers can do in an urban neighborhood, both directly and indirectly. It’s not just “presence”, but making sure the bad guys get caught fast. Also, getting other agencies involved, from housing violations to selling liquor without a licence at an impromptu sex club. (It has not come back.)
How much the police can do depends on their adaptability and the situation, but if they are good, they can do wonders. I’ve seen good hard working cops and many just getting by. There is a world of difference in the crime situation in a neighborhood over the years.
When only seconds count for life and death,
The police are minutes away.
