Did Trump Encourage Police to use Excessive Force During Arrests?

During a speech to Law Enforcement Officers on Long Island, it sounds like President Trump encourages the officer to be rougher with the people they're arresting.

Just take a listen for yourself and them form your own opinion.

Now, we're getting them out anyway, but we'd like to get them out a lot faster. And when you see these towns and when you see these thugs being thrown into the back of a paddy wagon -- you just see them thrown in, rough -- I said, please don’t be too nice. Like when you guys put somebody in the car and you're protecting their head, you know, the way you put their hand over? 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, okay?

- President Donald J. Trump

While the White House has officially said that President Trump was joking, it sure sounded to me like a clear directive to be excessively rough with innocent people - you know that whole Presumption of Innocence thing we have in the USA?

So what do you think? Was the President joking or was this a tacit instruction to be rougher when arresting people?
