I understand that's how it works, and your correct, a jury weighed in on the evidence at hand and decided that there wasn't enough to move forward with a trial.
I've heard that there were 12 witnesses and only 1 said they heard the no knock, but I've also been busy and haven't been able to hunt down anything more than internet hearsay source for that, and as you point out, it's done in secrecy so where were you able to get a solid source on that 11/12 number I'd love to get more information on it.
I hear you on your point that there should be a trial, or understand where you are coming from. This is a legit question since you've obviously given this thought and not just knee jerk reaction. As distasteful a no knock warrant is, they do exist and was granted here (used or not is in question)... but let's assume they were granted it, and didn't knock. They enter legally under the warrant, are fired upon and return fire legally. Shouldn't the anger be at the system, and demands
on that to change, and not a push to charge the officers who operated legally? If not, where do you think they deviated from reacting in a legal fashion?
