First off, if you read about 19th century America, communities provided security for citizens via watchmen, constables, town marshals and sheriffs. If that failed, vigilance committees formed.
Before cutting budgets for security, you first get rid of deadweight, like city managers, assistant city managers, bureaucrats of every shape, manner and form and legislative assistants for fat-ass politicians.
Of course this would cut into the voter base of the Marxists. But we don’t care. Or if General Sherman were brought up to speed about the situation in the 21st century, he might say: The only good Marxist is a dead Marxist.
I’m sure good ole Wille T. would have no problem with that.
