Hmmm...

Cleveland, Ohio (CNN)The head of Cleveland's largest police union is calling on Ohio Gov. John Kasich to temporarily restrict the state's open carry gun laws during this week's Republican National Convention following Sunday's shooting in Louisiana that killed three officers and wounded at least three others.

"We are sending a letter to Gov. Kasich requesting assistance from him. He could very easily do some kind of executive order or something -- I don't care if it's constitutional or not at this point," Stephen Loomis, president of Cleveland Police Patrolmen's Association, told CNN. "They can fight about it after the RNC or they can lift it after the RNC, but I want him to absolutely outlaw open-carry in Cuyahoga County until this RNC is over."

Very strong words from a person who is sworn to uphold the Constitution.
"I dont care if its constitutional or not"

While i disagree with limiting rights.  I do fear a blood bath and full out shoot out which will leave many dead which will lead to democrats getting more gun control.

Can a governor even issue a executive order which revokes a law giving someone a benefit?

I know during a national emergency the governor is given certain powers but not sure if it can be done in general.

I understand the concern but I don't it should be done. Huge slippery slope issues here.

Maybe he could suspend all rights and call martial law.  America is done.  Just need a little more to push er over.
