Is it true that secret agencies often kill people for knowing too much, or kill people illigally?

As in, man A knows too much, ASIO will send someone to kill him. Or, theres an undercover mission, they can kill anyone who is in there way/security blocking a door, etc.

Hmmmm, maybe i have been watching too many movies lol

Mossad hunted down and killed the Munich Terrorists - see the rather dull film 'Munich'.

"The Increment"

The Secret Intelligence Service (SIS), better known as MI6 has a cell comprised of operators from within 22 SAS and the Special Boat Squadron known as "The Increment"; they are/were the cream of the crop of SAS/SBS soldiers that are selected and sent specifically on SIS-supervised missions such as would have been the case in Richard Tomlinson's accusation that SIS had devised possible assassination scenarios for Serbia's Slobodan Milosevic.

It is not known if they are a permanent unit or whether they are only activated for specialist operations.

I believe you watch too much movies. Go outside and play basketball or something instead fo watching so much tv.

yes it is true. DUDE dont talk about this on Yahoo. your risking your self!! dont. i never told you this....

The trouble is, the man you sent to do the killing now knows too much, and so on

Yess because man A will reveal their secret and it will hardly be a secret agency then.

Where is your evidence of these outrageous accusations ?

i'd love to tell you...but i'd have to kill you.

To many Movies for you lol.

Only in movie plots.

yes and somtimes no

All the time....and they are watching you now......accept for the part about knowing to much.....
