Would you consider 320 botched federal police raids 'isolated incidents'?

Stuff like this seems to be happening more and more often, and I think the problem stems from misinformation (like we were given regarding the war on terrorism in Iraq), and from the mindset of the persons hired to do jobs like these. People do make mistakes, but it's also very possible that there is something more behind some of these incidents. Makes me think about the Ivins, D.C. Madam and Brandy Britton cases.
