Anyone know why this is all caps?

I like to imagine that Barret was emailing a terrorist threat to Shin-Ra and accidentally hit the capslock with this big ass gun hand and couldn't figure out how to turn it off, like a grandma who is using a computer for the first time. Marlene would've helped him out--because kids know all about computers--but she was serving at a bar because Tifa was out doing god knows what.
