Depends on what you are doing. I doubt that the NSA would tip their hand that they could decrypt such things even in the case of child pornographers. Anything that would be taken into open court would shine light onto where evidence, etc came from. The real danger from NSA decryption would be in their storage facilities. What you say now could come back to haunt you in the future depending on the political climate (e.g. the US falls into a police state where political prisoners are taken, etc).
