Point to consider: SWAT knew his work schedule, and the schedule of his wife and kids. Why not detain him when he's leaving work, and execute the warrant on the house simultaneously? Most likely, the same goal is accomplished without having to fire a single shot, and nobody has to die (citizens or police)
If the reports are correct, the police were serving multiple, simultaneous warrants. This is typically done when there is belief that there is some type of collusion between the suspects.
If you arrest one suspect or serve one warrant at a different location as the rest, it is reasonable to assume that the others will dispose of any evidence that remains.
Since what we hae read or viewed so far has been media reports, we probably don't know all the facts and know little of any of the other warrants served. Thus the polioce might have been much more concerned about other suspects and chose to serve the warrants at this time.
The bottom line is that the majority of posters in this thread do not have the knowledge base or experience to make educated speculation, yet feel overwhelmingly compelled to do so.
Regarding the over-arching issue in this thread:
I too have questions about our country's "war on drugs" but it's way above my pay grade, just as a Marine may have had questions about Guadalcanal, the Chosin Reservoir, 73 Easting, or Iraq and Afghanistan today.
But they serve anyway because that's what they do and who they are.
Just as the officers who served the warrants might or might not have had questions, but they serve anyway because it's who they are and what they do.
Just as there are those (NOT directed at you gsarg) who don't serve anything but themselves and criticize those that do on internet forums because criticizing is who they are and what they do.
