The thesis was clear, but it did not hold any evaluation aspect. I found the evaluation throughout each of the paragraphs, which associated themselves with the solutions to the problems to be exceptional. I noticed a fair amount of grammatical errors. I would have enjoyed a more indepth conclusion. The idea that crime should be fought from the top to be unclear. I assumed that it should be fought against the larger criminals more often than the insignificant criminals. I enjoyed the part on how pollution spreads. I would give this paper an A.
