That was a train wreck we saw in New Orleans, ... But if we can have a national plan that would address the search and rescue at this magnitude, (that) is what we're out to try to do.
The police have the power to search people's homes, to make arrests, to take blood samples and so forth as long as they have 'probable cause' to suspect that a crime has been committed. That is a fairly low standard.
The public has the right to know why the police took the action they did, and that information is available to the public only if search warrant affidavits and arrest warrant affidavits are public.
