The shootings of four police officers in different attacks across the country over the weekend have many people feeling compelled to show their support toward law enforcement.

People have been writing messages of gratitude inside Houston Police Department’s 24-hour prayer room.

Ray Hunt, president of Houston Police Officer’s Union, said he’s been hearing about that gratitude directed toward officers in many different forms.

He said it happened to him shortly before an interview with KHOU 11 News.

“A citizen walked by and shook my hand and said, 'I just want you to know I have your back,'” Hunt said. “A smile, a thumbs up to an officer who’s eating, a person in a restaurant who walks up and says thank you for the job you do, like the person who walked up today...those things can really lift an officer when they’ve been down from so much.”

Police departments all over the Houston area have been taking to social media to thank people for those meaningful gestures.

Pearland Police thanked a man and his granddaughters for the pumpkin pies they brought in and also gave a shout out to another man who came in with 200 cookies.

The deadly shooting of San Antonio Detective Benjamin Marconi marks the 58th fatal officer shooting this year. That’s the highest number since 2011, when 71 officers were killed.
