Re: Allegations?
The US constitution states that the government needs a warrant to invade your privacy, not a private company.
The constitution also states that the government may not censor speech; it does not say a private company cannot censor speech. So, what has happened is that many administrations, both republican and democrat, have "asked" -- with implied threats -- to censor ideas they find unacceptable. Technically, the government didn't do it, a private business did. But it was a threat. "Nice business you have there, be a shame if it was under investigation."
In the same way, Flock is not the government and therefore technically not bound by the limitations imposed on the government by the US constitution. It is a loophole that the federal and state governments exploit. If the constitution prevents you from doing, pay or force a private company to do it instead. The constitution would not allow any police department from running Flock type cameras, it doesn't address private companies running them.
