Trigger Jerk, thanks for adding your expertise to this discussion.
I know you didn't use the word 'paranoid' in a pejorative way. However, I will point out that you're not paranoid if they are really after you.
To that end, the more I've learned about this issue, the more cautious I have become. The attacks on the RKBA are so extensive, so deep and so broad, that I find very little to be in the 'inconceivable' realm. Keep up with proposed local, state and federal laws and I think you will be amazed as well.
So, in California, for example, I would not find it impossible that their Attorney General would issue subpoena's to insurance companies to locate so-called 'assault weapons'. Perhaps that is not likely today, but once the data is in somebody's file ...
Consider the rapidity with which the current hysteria is traveling, and extend that out for another year to 5 years. Hell, we could see firearms manufacturer's records seized to locate warranty cards for heaven's sake.
For me, I compare the upside and downside, and if the downside is unlikely but potentially devastating, then I take reasonable action to avoid it. To each his own.
