It would be really difficult to spoof the IP address and create valid TCP connections. Plus, your method would only work if you knew in advance that certain sites were currently being used in a sting operation. If you could figure that out, that kind of defeats the purpose of a sting operation.

We're talking about a very large sting operation, just browse a few of those, I guess?

it would be trivial to hack their wifi or insert a rogue device into their home network

At that point, you might as well hack into their laptop, put a bunch of CP on there, and then call the cops.

Forensic analysis of the hard drive would exonerate you though.

No. Anything an analyst could feasibly look at can be spoofed with root access. The only thing that could potentially approximate the actual age of a hard drive write is thermal annealing of the storage medium, but this isn't really true anymore with SSDs (and was never practical even for HDDs).

Yeah, but it's not that simple. You'd have to install the Tor Browser Bundle, make it look like it was installed long before. You'd have to change the MAC times on the CP files to indicate a consistent pattern, and make sure the victim doesn't have an alibi for any of the times you're putting down. But you can't backdate the download time to before the image was produced, so you have to do your research on that. And of course you'd have to get your hands on a bunch of CP without getting caught yourself.

I'm not saying it's impossible, but it sounds pretty difficult to me. Maybe I'm wrong though.

At this time you'd already be under arrest tough, and probably in a tiny cell for a while. That was my point, this is what trolls look for. Then, unlike with other trolling methods, I'm pretty sure you need quite the clever lawyer to get out of this.
