You reckon?
I seem to remember that terrorists in Northern Ireland all got early release!
The British Govt. caved in to terrorism over there big time.
And for those advocating killing all those involved in terrorism, can I point out that this has been tried before too? For every extremist you kill, you push at LEAST one moderate into becoming another extremist.
There is very little you can do against people like this. Particularly if they are willing to kill themselves to make their point. You can't make places physically secure against these poeople. The only way to stop this sort of attack is to know about it in advance. That means intelligence gathering. However, the Govt., to$$ers that they are, then use intelligence gathering as an excuse for all sorts of other underhand activities.
Whatever happens, we lose!
