For the same reason that I don't do facebook or any of that other social media stuff, I choose to remain inconspicuous. I'm a Grey Man, in age, appearance and in my lifestyle. I'm accepting enough visibility just by posting here at FR and certain other forums.
I could consider posting a dated target with my screenname, but my (portly sexagenarian) face? Thanks but no thanks, not for me.
I can blank out any means of photo identification and upload it for you or email it back for your approval.
Facial-recognition software.
Getting very popular with police, the faster the better, to handle crowds and identify individuals in e.g. commuter crowds getting off trains (another argument against using mass transit of any kind), this software is a threat to liberty.
I think posting photos of FReepers is a very bad idea, names or no names. Ditto photos of gun lines, gun purchasers, conventions and gun shows.
If you establish a group and let people know you're forming one, one of them will be an FBI plant just on G.P. anymore .... and because you're white, or a veteran, or whatever.
You cannot form a group by dragnet; you'll be compromised by Holder's People on day one. You have to work by "adlection", and even then your security is so-so. You can't relax and bloviate about the weapons you own or whether you have food and water, a special storage space in the country -- anything like that will get you flagged by the Communist-style Block Watchers of the future, who will serve, perhaps already serve, the domination-oriented diseased personalities who are attracted to political bureaucracy and secret-police type activities.
More than what the author advocates, we need backing at the State level: We need the imprimatur of a State as a bona fide Militia organization. Texas has a National Guard, callable by the President, and it also has a State Guard, which belongs to Texas alone.
