So if "We, the People," are unable to tell whom a terrorist is, haw can anyone? No knocks and masks worn by officers, regardless of expressed concerns by law enforcement, are an evil which ought to righteously be outlawed.
In this incident the perpetrators represented themselves to be "law enforcement" though their actions went way beyond what most officers would do. In a case like this these people would have been honestly justified, had an opportunity presented itself, to draw and fire as they were in fear of life and limb. So too would they have been justified had it been actual law enforcement at the "wrong" place.
If it is not possible to get a proper search warrant describing the person, place or things to be searched a no knock is definitely not the way to go. Biding one's time is probably much better as you can almost always wait for, or anticipate an exodus from a dwelling which would create a safer environment to take down a suspect with much better control and threat to the general public. It was unlawful searches which were performed by the British which caused warrants to be written into the constitution in order to protect us all. (Declaration of Independence, Bill of Rights Article IV)
I am sure by this time we are all of the opinion that these trespassers/terrorists were not police. This being the case it is all the more imperative that the safety of all citizens be ensured by no violation of constitutional rights for service of no knocks, which do violate citizen rights.
During the debates preceding the establishment of the constitution it was mentioned, on more than one occasion, that the rights of the people were so solemn that the violation of one persons rights was tantamount to treason. For this cause we were protected. Unfortunately the judiciary seem to feel that this is not the case and in so thinking violate their oaths of office, as well as their responsibilty to the public, as do police, when no knocks are requested and granted.
For this I say shame on them!
