Purchase several dozen donuts and drop them off at the police station and thank them for their service. Ask the officers that are present if you can pray for their safety and pray with them before you leave. If they say no, then simply let them know that you will be praying for them specifically today. When you return to your car, take a moment to pray for all the officers in your city. When you pray for them, pray for their safety and that God will give them wisdom to deal with situation they face today. Ask God to bless them and their families.
