There are a LOT of comments on that article and I just read some of them. It's a horrible tragedy for the fallen officer, his family, his friends... I think the perps are learning how to shoot around the vest.
Last June, an LAPD officer was shot in the line of duty. The bullet went in just at the edge of her vest, at the armhole and ricocheted off her spine. She survived but is paraplegic. Her daughter, her first child, was 15 months old at the time (now 21 months) and her husband is LAPD too.
What is scary about the officer in Oceanside, is someone from a nearby neighborhood took aim from a house and killed him just for doing his job nearby. It was obviously a 'fun" killing and that is scary as all heck...
