All salafi muslims are like that, these ones just carried out what is in their minds 24/7 365, and that is, killing kuffars. That is literally the only thing these people think about, they read that sahih al bukhari crap daily and keep braying 24/7 to get their chance to act out.
It must also be tough for salafi muslims in western countries, everywhere they look, haram, all the women who don't wear hoods on their heads are 'whores', people drink, eat pork. They should all leave the west and go settle in saudi arabia or join isis, that's where they'll be happy.
