I'm saying that in principle there's nothing wrong with focusing in on a specific problem, and doing so makes the legislation much more limited in the harmful effects it could have. It reduces the discretion of police officers in other investigations, investigations in which we as a society may not feel that what would otherwise be criminal conduct would be justified. It reduces recourse to criminal activity in those types of circumstances.
At the same time, even if it's focused just on the infiltration of criminal organizations, there's nothing about a narrow provision of that sort that is irreconcilable with judicial oversight. The concerns with respect to confidentiality of informants and protection of investigations can be readily addressed, as they are in the search warrant context and in the wiretap context.
