Guns. Over the weekend, two New York City policemen as well as a Tampa Bay police officer were killed by former felons. Who had access to firearms. I don’t know Florida and Maryland gun laws well enough to know if the killers (former felons) could buy firearms legally, or if they had to buy them on the black or gray markets (i.e., gun shows).
Either way, I’m pretty sure that most protestors and police agree that criminals should not have ready access to firearms.
Aside: Given that two armed police officers with body armor in NYC were gunned down without a chance, it puts the lie to the NRA’s notion that more guns are the solution, doesn’t it?
