Since governments have existed for thousands of years, the first step would be how do governments deal with crime, since they've been the power structure we allow to rule us. Is there a better way? I don't know, but looking at how it is handled now could give us insight into the cause and effect that government has on the population.
There is sadly no quick answer, and no way currently to address is substantively, since gov retains the sole power to initiate violence against humans. Basically, they hold the gun.
