Mike Lewis, sheriff in Wicomico County, Md., told Sean Hannity tonight that anti-police rhetoric from groups like Black Lives Matter can have dangerous, potentially deadly consequences for officers.

"It's open season on law enforcement across this country," Lewis said. "American law enforcement [officers] are under siege."

Lewis said that it all started with the lie of "Hands Up, Don't Shoot" in Ferguson, Mo.

"Everybody's scared to death to do their job, scared to pull the trigger," Lewis said. "The last seven days, we've lost seven police officers."

He added that President Obama hasn't condemned the killings of law enforcement officers, while he's quick to speak out about the deaths of Trayvon Martin or Michael Brown.

"Not once has he stood up and denounced the killings."
