Dear TX. RGR.:
On your comment:
" It seems to me the only rationale for a no-knock warrant is the possibility of evidence (drugs) being destroyed, or the imminent potential threat to an innocent."
I agree on the imminent threat to an innocent individual being a good reason for a no-knock entry, but respectfully in my opinion, it is the ONLY reason for a no-knock entry, and ask you to consider the following regarding no knocks and drugs.
If drugs are being destroyed, I don't feel it is justified to do the no-knock, because of these two issues: (1) If the purpose is "getting drugs off the street" in this war on drugs (that has been going on for over fifty years at least) then flushing them down the toilet results in that very goal, and
(2) If it is the wrong address (as in the Houston death) a totally innocent American citizen can be shot to death in his own home while trying to defend himself and his family against unknown people crashing in his door, who it turned out, were there with the intent of making sure he didn't flush drugs.
Please understand I am not Anti-LEO. (I am a Ranger historian in fact, and have a great amount of respect for the Ranger organization and have personally devoted hundreds of hours to the historical study of the Ranger service.)
But I am Pro-Bill of Rights vs. the Later Lawyer Crowd as well, and I cannot imagine how "secure within our houses" could square with a "no knock entry" to serve a warrant. You may have a view that would change my thinking, (as I would obviously give great consideration to the reasonings of a man who has reached the very high level of training necessary to be a Texas Ranger today)
But I just can't seem to understand how a no-knock entry, is squared with constitutionally serving a warrant.
