I did a gun control term paper back in the 1980's. 58% back then of gun crime was committed with hand guns, 38 or 39% was with shotguns, and only 3% was with rifles with only 0.5% with so called assault rifles. The dems keep going after assault rifles, which are used rarely but with bad effects, but day in and day out it is handguns. Also, if you took out the 5 biggest crime cities in the US, our crime rate would drop to about the lowest in the western world. Again, most crime is by young black teens and young men, with Hispanics being surprisingly a distant second. There are more Hispanics in the US than blacks. Hmm.
If concentrated effort was given to the root causes, gun crime would drop drastically. Like more police and patrols, like Miami. Miami's crime has dropped way down with the new Republican Hispanic mayor. They love him down there. Also, more jail time for repeat offenders, etc.
There is too much race baiting and hate spewed out by Dem politicians that really isn't true anymore. Compare Houston with Chicago. Houston has about the same percent of blacks, but more Hispanics than Chicago. Houston has about 700 gun stores with Chicago none.
One of the items in my research was 85% of crime is with stolen guns. Mostly from vehicles. So, if you carry, carry it with you, don't leave it in a vehicle unless you have to and find a way to lock it in. Friend of mine had a Glock 19 stolen from his locked pickup truck while he was at Cracker Barrel, but parked in a dark spot on the side due to being crowded. They punched a hole with a screwdriver or something under the door lock, and opened the door and found his Glock locked in the now broken console.
