Miscarriages of justice are unfortunately not uncommon, but if I thought I saw a woman being raped, a man being mugged, or anything even remotely suspicious, I still think a call to the bobbies would not be unjustified.

EDIT: Allow me to add, as it is probably more pertinent in your neck of the world anyway BW, that if the terrorists in question were white IRA fighters (an IRA faction, I know, since the mainstream branches have stopped the violent tactics), we would have no problem with this sort of ad campaign against them. But since the predominant terrorists in the US are Middle Eastern, liberals immediately think, "Oh no! The evil whites are going to stereotype the minority group!" I'm sure some will be racially motivated, but I think the majority are intelligent enough to report a white man buying bomb parts instead of the friendly Lebanese man who invited you over for a barbecue.
