Although the laws did not name names, it is clear that they targeted Aum. Secondly, Aum is generally discredited in Japan and almost unanimously feared by society at large. Thirdly, Aum is loosing members and is reduced to a few thousand true believers. It may well be both. It may be a move by certain leaders and a genuine change of heart by others, particularly by those who were never directly involved in criminal activities.
Religious movements can reform.
While I am certainly not comparing them to Aum, a case in point are the Children of God. It may survive, although probably only as one of the smaller Japanese new religions. The next few months will be crucial. A difficult passage will be when Asahara is sentenced, possibly to death. If the new Aum, or Aleph, will not protest it will disappoint some of the hard liners.
