Arguing on social media is fun because you get to know the thoughts of people you don't agree with. If a candidate sends in a lot of paid trolls, you'll get an bad impression of her followers. Recycling a limited amount of talking points makes you look very stupid.
The problem is some people totaly disrespect the law. These guys are supported by AK47-swinging drugsdealers. Educating law abiding citisens might save more lives but doesn't solve that problem. Normal policework does (and maybe legalizing drugs will cut the funding of their lifestyle)
