Obama plans broad gun-control

[Mach1]

this pisses me off so much i may have to go pop of another 100 or so rounds at the range this weekend to calm down!

you should put those rounds to good use and kill 100 tyrant leaders of this country!

[GeorgeG.]

So what if scenarios like these actually play out this term. If, and hopefully when, Obama gets replaced by a Republican, what would it take to reverse these new laws? Is this even a possibility?
