Correct . No one with the slightest knowledge of bombmaking would use a camping cook stove propane cylinder for an explosive device . The vastly more plausible reason for those bits of camping equipment being in the truck on the bridge is that folks have been camping in the area . and have been using standard cook stove fuel in such canisters . For the police to hold these up as evidence of violent intent is more than a little absurd . Unless they were emptied of their intended contents and filled instead with some sort of explosive material which they ' d have to demonstrate . Not that they ' d be believed by many here if they did . Also noteworthy is that the police did not exhibit a propane cylinder showing the sort of rupture which would be associated with an explosion . So they have NOTHING to explain the massive arm injury which the victim had . They appear to be attempting to spin the news in their favor , and some folks appear to be buying it because they tend to believe authority figures like police . Police would not lie to us !
