I had something similar happen to me...
And they took get this... My Modded XBox, and my 360, because they had hard drives.... They also took my Windows desktop, which made me to switch to mac
Anyway the cop lied to me and told me it would only take two weeks... Yeah right! More like 1-2 years.
Listen here this "evidence" collection is crap. The police are the scum of the earth. They lie to you, they take your property, they do not protect us.
So, some investigator found enough evidence of something bad that they took it to a prosecutor (or grand jury,) who filed charges, then the investigator wrote out an affidavit and signed it, gave it to the prosecutor who took it to a judge who then signed a court order in the form of a search warrant for your house- which they executed? Ok, sometimes that system has issues, but in general the checks and balances work. So- was it accurate, or was there a specific part of the affidavit that was untrue?
If it's a computer crime, then it's processed as a computer crime scene- that means all the computers are siezed. You can thank the past criminals who've used game systems, cell phones and other electronic devices to commit their crimes. If they didn't seize anything that could have been used in the commission of the crime, then they'd be lambasted if criminals got away with their crimes- so what's the alternative? If they don't treat every case the same way procedure-wise then they'd be accused of favoritism. Plus, a fair number of folks who come to the attention of the criminal justice system for one crime don't just commit one crime, so everything needs to proceed in a way that doesn't contaminate the ability to go get more warrants if other crimes are discovered.
You can look at every successful prosecution for a computer crime to see that evidence collection does indeed work. The legislature is responsible for laws that suck and laws that don't suck. The judicial system is responsible for allowing prosecution, permitting warrants and subpoenas. Detectives are more about justice than protection, though there's the protective nature of removing the ability of criminals to perpetrate more crimes.
FWIW, the police are allowed to lie in order to gain the cooperation of a suspect. While circumstances may change the advisability of using that tool, it's often the thing that gets a criminal to admit to something, or assist in the investigation. That means that suspects who aren't the actual criminal get lied to too- it's an artifact of the system.
All the computer crime cops I know are so busy dealing with child pornography and computers potentially used in other crimes like homicides that they would do anything to not have to process systems where a crime wasn't committed, let alone do all the paperwork involved with a case if there's no chance of prosecution. Most prosecutors wouldn't file charges in a case they thought they'd lose too. So, how about outlining where things when wrong in your case?
Heck, I've had way more experience having trouble getting cases open with local cops than having cases opened frivolously when my customers have been victims of computer crime.
