Police officers take an oath to protect all of us, even at risk to themselves. During my term as Suffolk Police commissioner, I saw firsthand what price officers from this and other departments paid at times to keep that pledge.

To echo the words of Police Commissioner Edward Webber, Collins is a hero, and we are thankful.
