Did The Department of Homeland Security shoot at a U.S. Airways Jet?

This from the Flight Safety Infoservice today -

London's Daily Mail reports that ballistics experts say the bullet may have been a stray, and not fired intentionally at the aircraft. The bullet was apparently losing velocity after traveling about three-quarters of a mile when it struck the plane from above taking a front to back trajectory.

...just keeping the topic up to date - hate to see speculation left undiscussed when there's more info coming in....although this isn't quite "facts" yet....

.40 cal is the second most popular handgun round out there. What exactly makes you immediately just to DHS?

Without evidence I dont(sic) see ANY correlation.

What evidence do you have that contradicts it.
btw, how's that High School English class going?
