it looked like the dog was attacking someone.

Just FYI, dogs don't wag their tails when they're 'attacking someone'.

I didn't see any tail wagging just a rush in the direction of the people. But I have also heard the contention that dogs don't attack with their tails wagging is also a myth.

It is unfortunate that the occupants didn't close the car door and this would have never happened. I don't defend trigger happy cops which may have happened here but also will not join the Jump to Conclusion Chorus around here which is poised ever ready to attack police at any hint of misconduct.
