Even if you do sue the gov't, it'll be at least a year before any kind of resolution that results in the return of that device. Them keeping my phone would be one thing, but if they also kept my laptop, I'd be screwed. My laptop is much more than $1k, and there's no free laptop with contract cell service I could use to replace it. Now I'd be without a means of working.
These kinds of situations make me really yearn for the days of replacing the internal hard drive of a laptop. I could swap out my daily use drive for a travel drive, which would be much less of a hassle than the options on offer for modern laptops.
