lol! 
What's to stop people from putting gunpowder in the bullets? That said I get where you're coming from, these are more like rubber bullets than anything particularly threatening at the moment and I get excited about anything that scares power hungry people 
Well, I don't get where you're coming from. Ammunition and its components are nowhere near as tightly regulated as firearms. People make their own ammo all the time, simply because it's cheaper than factory ammo. In most places you can walk into any gun shop and just buy bullets, gunpowder, primers, and shell casings by the thousands, no questions asked. If nobody was scared by that before, why would they be scared now? What's to stop people from putting gunpowder in the bullets? That said I get where you're coming from, these are more like rubber bullets than anything particularly threatening at the moment and I get excited about anything that scares power hungry people
