All gun reform needs to be on the same page, therefore, it needs to be federally mandated (just like the drivers' license and seat belt laws and auto insurance, etc). We cannot trust the states to do the right thing. Take Chicago for instance. It's a "gun free zone" yet the gun crimes are over the top and that's because criminals and crazies can get their guns in Indiana which has irresponsible and lax gun laws and then bring them into Chicago and wreak havoc. When that happens, republicans irreverently blame the "gun free zone" rather than the abject stupidity of the irresponsible Indiana guns laws. Indiana (along with other red states with irresponsible gun laws) is not doing the right thing. Suppressors are dangerous, especially in the wrong hands, because there is only one use for suppressors and that is to kill human beings -quietly- making it very difficult to identify the shooter. (Don't make me laugh by telling me hunters need suppressors.) There is a great need to regulate gun suppressors and states, especially states with irresponsible and lax gun laws, should not be allowed to make that decision. Using the "protection of hearing for hunters" is a ridiculous, absurd excuse to deregulate the suppressor and is irresponsible as there are other measures to use such as ear plugs. Doesn't surprise me at all that irresponsible republicans are behind this bill.
