I am betting the hi-cap ban is going to be a definite as will an "Assault weapon" ban. The cost of EVERYTHING that goes bang will go up.
Good news though, all your current guns are going to be worth a whole lot more now.
Sorry thing is that when violence rates go up, they will not likely relax any of these new restrictions. Scarey thing is what comes AFTER this round. When the next shooting happens (and it will), will we start seeing gun confiscations? Remember, the FBI estimates we have about 200 million firearms in the country. If they all stopped making guns tomorrow, there will still be guns in the country. The only way to get them off the streets will be to go house to house and take them away from people. Even then, the guns will still be on the streets. This is when things will get real scarey as I know a lot of Americans will fight rather than give them up.
