There is no "enforce[ment] in good faith", and the evidence is everywhere. The Patriot Act is used domestically for any and every type of law enforcement investigation, far beyond what it was supposedly intended to be.[0] We've seen civil forfeiture become essentially a license to steal for LE agencies.[1] The government has stretched the meaning of the "exceeds authorization" component of the CFAA to the point of being almost meaningless.[2]
The point is this: the natural tendency of government is to stretch any power it is granted to the absolute max. We have reached a point that an assumption that government will exercise enforcement in "good faith" is simply naive. I assert that there is little evidence to the contrary.
