The thing about allegations is that they can be made by misinformed or biased people. I allege that a swat team broke into my house yesterday looking for a lost puppy. Prove me wrong.
Allegations only have merit if they come with detailed descriptions of what actually happened, and not just opinions about possible motivations.
Or does it suddenly become legitimate if enough people present biased allegations?
Note: I'm not saying the DOJ can't be using this operation as an excuse to violate the rights of the companies they target. But the theory that they are is a conspiracy theory. And those are especially hard to accept when their only evidence is a bunch of opinion pieces.
Also note: These companies were practically guaranteed to make a stink about this operation and blame Obama for it regardless of if their allegations are true. Any government action that even looks sideways at guns (or religion, for that matter) is definitely going to be blamed on Obama. Their obvious bias is going to make it that much more important that they actually prove their claims.
