I honestly don't think police officers get enough praise for doing what they do. They put their lives on the line every single day for us.
Body cam of this officer in New Jersey shows him saving a man's life seconds before the guy was hit by a train. The officer was called to check on the condition of a man on the train tracks. When he got there, he noticed a train coming. So he took off running, trying to get the attention of the train and of the man on the tracks. Luckily he got there just in time.
