No one can entirely deny some bitcoins are being used for illegal activity, for example funding drug dealers and some other criminals, but these are punished themselves not bitcoin.
Bitcoin is a currency and should be treated as one, being used by bad people isn't hard to expect at all.
At the first mention of the fact, there were zero regs involving Bitcoin so it was open season. these days, the press and the polictically controlled media centers just put it out there ever so often to keep the fires burning because they hate bitcoin, it is no more or less used than FIAT for crime
