I'd agree with this. If some asshole tries to invade my home my guns should serve as a serious deterrent. Conversely, if the government sends M-1 tanks rolling down my block, I'm pretty much fucked just standing there holding a shotgun for "protection against a tyrannical government".
Hey....if I can own an AR-15 why can't I have a tank? That would be so cool....even if it was just a light armored vehicle like a Bradley or something. Instead, they have to draw the line at automatic weapons. What a buzzkill! I sure could have used a tank during the recent flooding we had here in Texas!
I'm not sure how effective M1 tanks were against an insurgency in an urban setting like say, Fallujah. I'm sure they provided cover.
No, even if you could have a tank, you still can't match the arsenal the federal government has at their disposal. But matching them at every level isn't the point. It's giving them pause. Unless it's gotten to the point of extermination and not just arrest and seizure, some asshole with 3 bold letters on their vest and armed with a rifle is going to be kicking down your door. At the very least, you should be able to match that level of force.
I just don't buy the argument that the 2nd amendment as a check against the federal government no longer applies because we're beyond the age of muskets. Were people allowed to have cannons and mortars back then?
