I gotta say I could take out thousands of people within 2 hours of this message posted if i had the intent and Im not trained.
IT involves a plastic decomposing cemical in storage in unguarded tanks in open fields behind razor wired double mesh fencing in a high populated area . Which ever way the wind is blowing everyone for a thousand kilometers is dead and more and more spread over years of agony and deformed births etc ,I'd be dead instantley too about 1 min after the high powered shots went through and one micron of this stuff got to within 6 feet of me.

Anyone could even take a sharpened pencil or two on board any plane and do anything they wished.
You could of taken a small craft down into an open aired arena during the opening of the commonwealth games and taken out your Queen,our primeminister,the opposition leader and head of our state among just a few.We could see the arena when we took off in a piper cherokee headed for King island surfing and we didnt get checked for a thing and I got the front seat with the other controls right in front of me with only the pilot next to me.
Too easy.
