In Kalamazoo, MI, students are protesting the violation of their rights via a ban on carrying a concealed weapon on a college campus.
The article linked above isn't clear if the ban is legislative or if it is a ban by the individual schools.
If it's the former, instead of protesting, these folks need to stand up and just do it. Don't let a law leave you vulnerable. I don't think you need permission from the government to carry a gun, and if the government thinks otherwise, let them catch you. The only way they will is if you needed the gun.
If it's the latter, live your principles and go to one of the (very few, apparently) schools that do allow carrying concealed handguns.
