Police departments distance themselves from Trump's comments encouraging police violence

The president seemed to encourage police violence in a speech Friday.

Speaking to law enforcement officers in Brentwood, New York, Trump said, "When you see these thugs being thrown into the back of a paddy wagon, you see them thrown in rough. I said, 'Please don't be too nice.' Like, don't hit their head and they've just killed somebody. I said, 'You can take the hand away, OK?'"

He added, "When you guys put somebody in the car and you’re protecting their head you know, the way you put their hand over [their head]. Like, 'Don’t hit their head and they’ve just killed somebody, don’t hit their head.' I said, 'You can take the hand away, OK?'"

Shortly after the speech, the Suffolk County Police Department, whose jurisdiction is the county in which Trump spoke, came out against the remarks.

"The SCPD has strict rules & procedures relating to the handling of prisoners," it tweeted. "Violations of those rules are treated extremely seriously."

A subsequent tweet read, "As a department, we do not and will not tolerate roughing up of prisoners."

Following the Suffolk County Police Department's tweets, its counterparts across the country also took to social media to express their dissatisfaction with Trump's remarks, and to reiterate their policies for handling people in custody.

"Seattle’s police officers have embraced reform and have worked incredibly hard to build community trust," O'Toole said in a statement. "We do not intend to go backwards.

We remain committed to our principles and reject irresponsible statements that threaten to undermine our relationship with the community.

"Any unreasonable or unnecessary application of force against any citizen erodes trust at a time when we need support from our local communities the most," Harrison said in a statement. "This is not a binary choice of either protecting the public or protecting a person's rights. We can and we must protect both, and NOPD will continue to lead the way in adopting policing reforms that do just that."
