Which file are you looking at? In the clean May data, "inmate" is used in the "Invovled_Party_Type" field to indicate a PO directly involved in a firearms discharge (i.e., a PO who shot someone or was present when someone was shot). For example, Jason Van Dyke is listed as "inmate" on CRID 1072125 (Laquan McDonald).

What's the difference between inmate and witness when there's more than one inmate, but police officers are listed as both inmates and witnesses?

Just realized I didn't reply yet! Generally speaking, the "inmate" POs allegedly did something wrong, while the "witness" POs just saw what happened, either as it happened or the aftermath. For example:

1079080 PO who fired gun and his partner are "inmates." Other POs who arrived on the scene and arrested a second, non-DoA person are "witnesses."

1079661 2 POs who fired guns are "inmates." Of 2 POs on scene who didn't shoot, 1 is an "inmate" and 1 is a "witness." Not sure why.

1073787 2 POs who fired guns are "inmates." 3rd PO who was with them but didn't shoot plus 2 more POs who didn't shoot are "witnesses."
