“Opinion polls suggest that a majority recognize a right to bear arms, subject to reasonable regulations protecting public safety”. <—— Oh yeah? Who says so?
The government cannot issue any constitutional “regulations” regarding the use and availability of firearms. The 2A is a guarantee to the people that we’ll have the means to overthrow an overweening and tyrannical government if it ever should come to that.
It means that the fox isn’t allowed to guard the henhouse. If We the People allow this then we become the chickens.
This big fight is over what is a "reasonable regulation". I have seen that polling question before, and it almost never defines what respondents consider reasonable. When the clarify what regulations are actually being considered support is often anywhere from under 40% to barely over 50%, depending on what is proposed. I.E. I personally think background checks should be improved, am not convinced that Schumer's bill contains any improvements to the current background check system, and am certain that it contains numerous provisions that are either irrelevant or counter-productive.
