To use your fire problem analogy, your solution is to take away the Fire Dept and turn off the water.
No in his analogy I think it is more like this, where as he will be adding more fire departments (taxes for more law enforcement or fire enforcement) and more water (taxes for more fire hydrants) = (more rules and law enforcing of those rules, that is equal to more water), in order to battle the fires, in which he see's as out of control assault weapons being used for violent acts.
Out of control assault weapons? You mean this happens every day? Damn! I haven't seen it in the news.
And just exactly what is an assault weapon? Black and scary looking? As I said upthread, Oswald killed JFK with a bolt action rifle.
Now, take a look at this:
Which one would you consider an assault rifle?
Actually, that's a trick question. All 4 rifles are the same rifle, they just have different stocks and, except for the 4th one, they all fire the same cartridge.
