I write FR software, and this practice irritates the fuck out of me. A common phrase in the industry is you can't anticipate what stupid users won't do, and this is a clear case of end-users sticking their fingers into powered light sockets, at the expense of the general public's safety by the very agency enlisted to protect the public. The stupidity is amazing. If there is ever any regulations around FR's use, probing with doctored or "looks like" images needs to be illegal or at minimum no grounds for any warrant of any kind.
