It doesn't even need to be infiltrating TOR. They caught a kid who called in a fake bomb threat to get out of a college test because his connection to the TOR network coincided with the threat. You could relay your traffic through one or more VPNs before connecting to the TOR network if you trust the companies not to keep logs or be beholden to the FBI/NSA. But realistically your only friend in a worst-case scenario is the fairly reasonable hope that these agencies don't have the ability to parse all of their raw data, that they wouldn't waste time looking for you, and that you're not important enough for them to show their hand to everyone else and reveal exactly what they're capable of.
