Perhaps my tinfoil hat is on too tight,but the UN does not believe people have the right to self-defence and using body armour is a form of self defence. Now the people that are directly behind banning the sale of Level 3 & Level 4 body armour to the public is our government and law enforcement. They may be afraid of criminals getting their hands on it but it is also keeps it out of the hands of law abiding citizens for no good reason.
Banning it from sale to the law abiding citizen will still not stop it from getting into the hands of criminals as they don't care about the rules.
The sharia law thing was out there I admit, but I was on a rant and it just came out.
Without power, the people are simple to manipulate.
