Even if he was trained via a **traveling band**, he would known way more, than what he showed. Thing is, if his shooting ability is that bad, how did he pass F/C or L/N at all? I believe it was said here long ago, by the past AMU commander,.... I can train a monkey to shoot,... the rest is much harder,..or something to that effect.
If he went to the point of having body tats, of past deeds/tools, that the kind of shit you don't ever forget ,....
** he is not old enough for that anyway.
edit for fat fingers
