Foxy,

So you agree that Islam is a problem?

Do you think think that terrorists respect gun laws?

There are so many ways to obtain firearms that no terrorist is going to bother with getting one legally.
The internet is full of ways to make them and doing so is quite simple, machinists and fitters make much more complicated things as a matter of course in their daily jobs.

But what terrorist needs a gun?
There are cars, petrol, diesel, coal, electric timers for bombs and starting fires all freely available for purchase at your local legal outlet.
And your local supermarket sells bomb making materials; have a look on the net.
Then there are airplanes; remember the Twin Towers?

Is Mise,

No I don't agree that Islam is a problem.
Extremism and mental illness is.
And they have existed throughout history.

We certainly can't stop all fanatics
and extremists or people with mental illnesses.
But we do have laws to at least try to control
things and make things more difficult for the
mentally deranged. Gun laws have been put in place
for that reason. They are only one example to make
our society safer for us all.

Is Mise,

Here's something positive that came from Sept. 11th:

We still have selfish, greedy, incompetent, useless people whose voting power allows them to exploit the rest of us !
Not even several more 9/11's will change that !

individual,

We've always had those kind of people.
It has nothing to do with September 11th.
