I have to admit this is kind of funny and creative, but obviously it isn't right to go around stealing these things... he should BUY his own materials for his "artwork"!
Not only that, he destroyed some of them for his art.
If the thing could be taken apart with no holes, rips or screws sticking out and they perform their function, I must just say “get outta here”.
But he chopped some of those barrels up for this. Are they owned by the state? Taxpayer money?
Being unemployed results in alot of free time.
