Lots of people can and it becomes a lot more obvious after you time stretch/process it. Important to have 320 kbps files at the very least for samples, and preferably more like 24 bit wave.

@ the OP: you should be able to tell by looking at a spectrum analyser. A 192 kbit mp3 will have a sharpish rolloff toward the top end AFAIK. but I don't know what specifically to look for, and there are other explanations, like someone put a low pass on it.

320 kbps has very little loss of extreme treble frequencies, whereas at 192 kbps and below it is cut out a lot more. If you see a sharp drop around 16 kHz in a 320 kbps MP3, you can be sure that it's been re-encoded from a lower source (that is if people are actually dumb enough to do that).
