Bullshit, period. The CHP workers were just plain wrong to release the photos unless they go through their public information office. Ya, once out they are in the wild, but they shouldn't BE in the wild. The boss has control, the pics are CHP property. Suing the CHP will probably be worthwhile to the family ($$$, hey I pass no judgment on that) but it will Definitely tighten up any loose cannons at the CHP.
The workers that did this should be held strictly accountable for any pain and suffering by the family through their negligence and the CHP must be made to enforce that on the rest of them.
Oh, BTW I am in that line of work and it would never occur to me to pull such a stupid stunt.
