We know that police and government are not liable for damage caused in the course of warranted searches. We also know that people who are not suspected of any crime can have their property searched and seized pursuant to a warrant.
Are there any enumerated rights to the speedy return of property seized for evidence, or for compensation when police detain property for so long that the owner incurs damages?
As an increasingly common example: Police can seize entire computer systems. There are all sorts of constitutionally-derived safeguards to ensure that the seizure and search are "proper." But I can't find any law or custom pertaining to how long the police can keep a computer, phone, or data storage device. And I have heard that they will routinely keep such items for weeks or months. When the computer(s) seized are someone's work machines then that person not only loses time and money to replace them, but may also incur damages due to the inability to access data that wasn't backed up offsite.
(Why the police do this with information systems is bewildering to a techie with some IS security background like me. Until I was shown some real-life cases to the contrary, my understanding was that SOP for data drives is to get them duplicated immediately. At that point a duplicate could certainly be returned to the owner without imperiling the search of the data, or its use as evidence.)
The indefinite detention of movable property seems incongruous with the treatment afforded to dwellings. E.g., I have never heard of a residence being seized for search and cordoned off for the duration of an investigation and prosecution. Instead, CSI is brought in for at most a few days, and once they decide they've done their job it's opened back up to the owner.
