The problem with a pit bull is that it has a jaw structure like a Great White Shark and a pea size brain.
Okay, the pit may act like a "pooddie" cat most of the time. However, if it "flips-out" it can kill three infants and 2 kids in less than a minute. These dogs do not belong in public areas.
Bengal tigers perform on stage and act very docile. However, if they get provoked or flustered they can slaughter 50 people before authorities have time to react. That is why they are not allowed to be domesticated. Pit bulls and Rotts do not belong in public.
If people want to own them they should be charged with manslaughter and sentenced to 25 years in prison if their animal attacks and kills humans. Less time if the human is only injured -- maybe only 15 years!
Reminds me of Roy from Sigfield and Roy getting attacked. Roy said after the fact, that a lady with big hair in the front row freaked the tiger out, so the tiger grabbed Roy by the neck and took him backstage to 'safety', almost ripping poor Roy's head off in the process.
The critter may 'mean well', but a 150lb Rottie, a Pit Bull, or a tiger have jaws and teeth capable of doing serious damage.
