How's this for product placement...

It seems that a gun manufacturer has been promoting a product (handgun) of theirs that will be on TF4, and are showing a (photo-shopped) image from the movie.

WTF? A movie that is essentially aimed at kids and teens (being toy-related), is being associated with the promotion of handguns, in a similar fashion as GM cars?
Is this how Michael Bay doesn't pay for anything, by having all the props be tied up in cross-promotions?
