Yeah, that is a puzzler. If I was guilty, there's no way I would write out all that stuff (even if attorney didn't stop me)... it just gives too much info over to the prosecution.
Now, if I was innocent (and desperate to keep my kids), I might figure I wouldn't have much to lose in trying to defend and/or respond to some of the points being raised against me in the custody proceedings.
If BC is "crafty" enough to (supposedly) try to get his wife's card swiped at LTF to place her there, and clever enough to intentionally go to HT, orchestrating phone calls to create alibi, it certainly seems inconsistent to then go and put any more than absolutely necessary in a public record affidavit. [ That is, if he's guilty ]
If he's innocent though, then maybe I can see it (the statements in the affidavit at least)
Just MO...
