This is hardly SOP in my experience. Door bashing over a cell phone?! Seriously?!
No.
Serving a warrant in support of felony trafficking and possession of stolen goods. Remember, the value of the item(s) in question have very real relevance over the type of response law enforcement engages in. If this was some guy's 5 year old Motorola Razr, a 'cell phone', it'd be valued in the double-digits of dollars (if that much) and would engender a very different response.
Instead, this was an undisclosed prototype device that carries real and significant impact in a multi-billion dollar industry, the theft and grand public exposition of such is valued far, far beyond that of any dollar value attached to any 'cell phone', even a retail iPhone. This puts it easily into the felony range.
And yes, when a search warrant is being executed, and there's nobody home, the door comes down. Doesn't matter if it was a stolen prototype, or suspected drug possession, or a fugitive potentially in hiding, or whatever.
Apple didn't write up the warrant, or send out the police. And insinuating that Apple is applying blackmail type leverage against DA's and superior court judges and multiple groups of law enforcement agencies to get this kind of response ... especially without even the tiniest shred of evidence is irresponsible and irrationally paranoid. To what end? It doesn't serve Apple's purpose to attempt such crazy tactics. Anyone would be able to expose them and then Gizmodo's legal troubles of grand larceny, etc, etc, would be a shadow of a whisper compared to the legal trouble Apple would be in of attempting to influence and corrupt judges and DA's.
Do you honestly believe Apple would gamble *everything*, a gamble of incalculable risk and so easily exposed, to try to force this sort of response? Please.
