Maybe that is the theory, as those words, and the other tripe he came out with, blaming everyone but the sorry system he has presided over for over a decade (how the heck can you figure it's up to a geographically vast, leaky bordered 3rd world shambles to police who decides to leave their shores, versus what our happy campers in immigration decide to stick out the welcome mat to????) simply showed him up for the human loss of plot that he is.

Imran Khan: This is the result of a weak government and the 'war on terror'

This is the result of the existence nihilistic anarchists who do not value life, brook no argument to their... rather limited and generally unpopular... world view, who like to kill and have minority willing audiences for their sad, selfish, brain-dead, cowardly actions (ambushing civilians is not that skillful or 'audacious'*), mostly in some media and those they turn to for 'analysis' or 'comment' as it's good for ratings.

Take your pick.

Addendum-

*BBC - Who carried out the Lahore attack? - '...a similar number of men staged an equally audacious attack.'

Googled:

2. Unrestrained by convention or propriety; insolent.

Not sure it's quite the collection I'd first go for.
