Not really. People get arrested for old oustanding warrants all the time, search warrant backlogs are pretty common. In fact, in general it is a good idea to back off a bit. It creates a false sense of security in the suspect, allowing better effectiveness when warrants are served, due to suprise. I know there is a "but they will destroy the evidence" protest, but in most cases, by the time a warrant is available the evidence will either be long gone, or completely overlooked (the stupid factor), this is one of those cases, he had plenty of time to wipe relevant drives between the announcement of a police investigation and the warrant serving.

The use of a raid force on a person who is not known to be violent and/or uncooperative is just excessive.
