And, the way I read the story from several stories, is that Chris Kyle was not bragging, but was being interviewed, was asked about it and plainly stated what happened.
Ventura was disrespecting a memorial SEALS were having for a lost member.
IMO, and I assume the events are true, fat ass wannabe Ventura got what he needed and deserved.
And, again IMO, by sueing Mrs Kyle, Ventura deserves some more medicine.
YMMV.
