I may be off-base here, but the fact that the no-knock warrant was given in parallel with a regular warrant (allowing the cops to choose which to execute on) tells me that not enough due diligence was done to issue the no-knock. I think if you're going to send in SWAT with a finger already on the trigger (which is essentially what you're doing with that warrant), then the threshold to issue that should be extremely high. You have to be 100% sure of what you're doing. Sending cops in under those circumstances and then expecting them to show all the restraint of a normal warrant is unreasonable.
