Unfortunately, history is not on Cranley's side.
Back in the early 70s Kansas City, MO engaged in The Preventive Patrol Experiment where they found increasing or decreasing the police presence in neighborhoods had no real effect in preventing crime.
Nevertheless, he has added more city employees & circumvented the City Manager to give the employees raises in the face of a looming budget shortfall.
Simpson, OTOH, wants to invest in the city in an effort to create jobs & opportunity thru infrastructure investment that will also help repopulate currently desolate places where crime can easily take root.
More responsible, educated citizenry with good paying job is the answer to crime prevention, not throwing away money on men in uniform driving around in tricked out gas guzzling Batmobiles.
