The amount of police force (time, money, officers, etc.) used to arrest a few suburban basement-dwellers is minuscule compared to the ongoing efforts against petty crime. I'm sure the expenditure was negligible. There were only six kids arrested.
Now, if they had arrested a few hundred civilians for "suspicion of conspiracy to defraud and infringement of copyright law," which I would imagine is possible, probably, that would be absurd.
That is a scary thought.
