Of course. So what do you do? Turn a blind eye? It's obvious imposing more individual regulation doesn't work.
If you look at most laws regarding pet keeping of any kind they are pretty comprehensive and simultaneously ambiguous the government could step up at any time and start doing its job. As seen in this incident the government did absolutely nothing to prevent this occurance with AMPLE cause and opportunity. This incident could have been easily avoided and was practically a bi product of the combo of actions taken and not by the government/sheriff. We don't ban dogs because of dog fighting or neglectful pet keeping we punish those who do so and do what we can to keep animals out of the hands of offenders.
