ban all sale and possession of guns for a 5 year period in America. after that 5 year period, see if the number of gun homosides are higher or lower than they was 5 years ago. people canot do gun kills if they do not have access to buy the gun.
for the record, as it is now, I am all for trying this experiment. however, if the ban is never placed and the experiment carried out, I strongly support felons being allowed to purchase a gun unless it was a violent felony. drug offenders should be allowed to purchase a gun until they are nationally banned.
it will take 50 years for guns to truly not exist anymore. most will be disposed of. but after that 50 years, we need to use non-lethal force like lazers and tazers that immobilize suspects. there is no use for lethal force in the untied states. there are too many innocent children being killed by cops. homeowners and cops both need to only be allowed to use tazers/lazers when guns are eventually banned (and they will be). it will probably be about 2040 or 2050 until America is finally intelligent enough to ban all gunpowder weapons like a simple revolver.
