Sonora Rebel has a very dangerous point.
Have an open carry protest really in NJ? Well I don't know about you but the NJ State Poilce is a very very strong and well trained organization.
The last thing I would want, or anyone would want, is for the NJSP to assemble their tactics unit and show up at the protest.
Two things that sounds really bad about this. Protest and guns. Introduce both into the picture at the same time and I would bet my property that the NJSP tactics unit would show up in numbers you didn't even know existed and every single person would be arrested, not dispersed.
If you want to protest about this issue, do not carry at all. Not even a holster.
Either leave NJ or get a group together to organize a petition and go about this the right way. With verified signatures from registered voters. Anything else would cause a very dangerous situation and there is a very very high probability someone will get killed. Thats the honest truth.
