New York Mayor Michael Bloomberg advocated police officers going on strike until lawmakers tighten gun-control laws.

With Piers Morgan on CNN last night, Bloomberg argued that President Obama and Mitt Romney need to address gun control because “48,000 people will be murdered with guns in the four years, the next four-year presidential term.”

“I think there is a perception in the political world that the NRA has more power than the American people. I do not happen to believe that,” he said.

When asked why Americans weren’t angry enough to demand stricter gun control, Bloomberg said he would take it a step further.

“I don’t understand why the police officers across this country don’t stand up collectively and say, we’re going to go on strike. We’re not going to protect you. Unless you, the public, through your legislature, do what’s required to keep us safe,” he said.

“After all, police officers want to go home to their families. And we’re doing everything we can to make their job more difficult but, more importantly, more dangerous, by leaving guns in the hands of people who shouldn’t have them, and letting people who have those guns buy things like armor-piercing bullets.”

Bloomberg said that while the Second Amendment is a constitutional right, “the government also has the right to have reasonable restrictions.”

“Not selling guns to minors or to people with criminal records or a psychiatric problems or drug addiction problems would be reasonable restrictions,” the mayor said. “So you start out with that. That we can have guns but not every kind of gun.”
