Same thing with Ross Albrecht. They got his laptop before he closed the lid. And this is a good point about the fear over chain surveillance companies; they grossly overestimate their abilities to sell their products. The VC's I know in the space don't like them for this reason, and mostly they're used to track exchanges and businesses that are being shady, not individuals. These cases are usually long expensive affairs to put together, and ultimately having access to the criminal's phone, computer, email, or iCloud is critical for an actual case, otherwise you're making a statistical guess, and as more people use a network, the data set spikes, and the probabilities become worse. And when small circular economies build, and layers are built, then the main vectors blockchain forensics lever (CEX's) start to dissipate. I've heard some CEX's haven't integrated the LN for this very reason: it's too private for their AML rules and blockchain forensic capabilities.
