What has been posted by “many Freepers” is demonstrably false.
Certain breeds, of which pit pulls top the list exhibit certain breed specific tendencies among which are aggressiveness and high fear thresholds.
Under IDEAL circumstances they can be for the most part trained to control those inherent tendencies.
Most are not trained however by a professional and are NOT managed under “ideal circumstances. This amounts to a loaded gun with a hair trigger being wielded by someone who has virtually no firearms training.
