To sum up the bad guy's assertions:
The bad guy's argument is that the CI stole his MJ plants, and in doing so committed a crime, and in doing so nullified the warrant's legitimacy. Being wary of having his MJ grow burglarized, he was quick to respond to people at his door presumably to force entry; people he did not, of course, realize were the police. He fired twice through the door.
"“In reality, the informer did not 'observe’ marijuana plants, he stole them,” Broccoletti argued..." Broccoletti is the bad guy's lawyer, and the burglary of the MJ grow is pivotal to the defense he is mounting. That the CI committed the burglary and that the police knew that are his assertions.
A veritable poster child. At best, he's an admitted grower, and presumed user, who shot through twice through a door at a group of police serving a knock warrant, killing one. At best...
But that's a drift.
Back on target:
How many documented instances of people using computers to send police to the wrong address are there? Of those, how many warrants have been served, or exigent circumstances exceptions to the warrant requirement made? How many people have been injured or killed? I'd like to know, if anyone happens to know.
