Two states, Indiana and Missouri, are considering legislation requiring police departments to have body cameras for officers.
The legislation, which has been passed by both chambers of the legislature, requires that cameras be used for all arrests.
The cameras would also have to be recorded on video and stored in a location that would allow police to be audited and to search the footage.
The law would not apply to officers who are in the line of duty.
Lawmakers from both chambers also have introduced bills that would require police departments nationwide to have cameras in the field by 2018.
