ELI5: Where do they get the "other people" for a police lineup?

Where do they get the people other than the suspect from for police lineups? Are they just paid actors or something?

The TV type line up is these days mostly replaced by the photo line up.  But traditionally they got other cops, people off the street or even criminals to fill in the slots.  With the photo line up you use mugshots.
