As much as everybody would like to make guns a conservative vs liberal issue, it really isn't. I've got many liberal friends who are ga ga over their guns. So they are always going to have a huge battle to get drastic gun laws changed. Like I said before in this thread, they'll most likely go another route, such as preventive measures rather than taking guns away.
The American people as a whole are pretty easy to read. It usually takes a shocking big disaster of some type to get the ball rolling. Such as 9-11. If the airports had been proactive in their security issues, the public would have raised hell over the security body searches, x-rays etc. But when 2000 people get killed and 4 planes go down in one day, that tends to change people's minds in a hurry. I suspect that we are one or two huge mass shootings away from getting the ball rolling towards these more preventive gun measures. These crazed killers seem to want to one up each other when it comes to mass killings. I fear that the next well planned out "big one" could be a 100 people or more. But another school shooting of a class full of kids would also probably tilt this country into doing something different than we are doing now.
