The Fremont "pit bull" is an American Bulldog, just like the Iowa attack at the Labor Day parade (also reported as a pit bull the first day) is an American Bulldog.
Troubled dogs come in all shapes, sizes and breeds - and all of them were showing warning signs before an attack. The dog in Fremont had a history of issues and is the exact same kind of dog in all dog attacks - a poorly managed and owned dog with a crappy temperament.
If Diana Diamond and others are truly concerned about protecting the citizens of Palo Alto, the solutions are really simple:
1) Enforce the leash law
2) Enforce non-breed-specific Dangerous Dog legislation
3) Proactive spay/neuter programs, especially in low-income areas
Then again, the Diana Diamonds of the world aren't interested in real solutions, because solutions aren't newsworthy.
It's a shame.
