... whether a homegrown terror group with little funding could get this crucial information
So what? A homegrown terror group with little funding still won't be able to carry out a credible attack.
More fear, more perpetual war
"Canadian woods"? Are you kidding? It is where the woods end, north of the tree line, that things start to get challenging. I have woods in my backyard and there is wifi access there. Nothing challenging about it!
You're flat-out an idiot if you give your DNA to any database of any kind anywhere.
I disagree. The "standard" 67 Short Tandem Repeat (STR) Y-chromosome markers used for paternal-line genealogy are perfectly safe, with one exception. The exception is an extremely rare mutation of one of the markers (DYS410) which carries significant medical information, but it is so rare I have never heard of anyone having this mutation (although someone must have or we wouldn't know about it). So Y-chromosome testing for genealogical purposes is pretty safe. Dozens, hundreds, even thousands of men all share the same values for these 67 markers.
So it's more like the Bible, then?
Amen to that! But I assume you are talking only about the New Testament of the Christian Bible, officially compiled and rewritten by some committee in the 4th century A.D. from prior works, some of which were composed before the birth of Jesus but which were not included in the Old Testament.
