Research conducted over six jurisdictions has found that there was not a discernable difference in the use of force exerted by police with a camera on, but more significantly, police wearing body cameras were more likely to be assaulted by a suspect. It is suggested that the presence of a camera may escalate an already heated situation between the police and an individual. 
It is suggested that although wearing of a body camera by police is supported, the level of trust towards police with the use of cameras has not increased. It is argued that they are being used as tools by officers to collect evidence against the citizen and vice versa, further increasing tensions.
A further concern that eradicates trust is the use of the footage. The release of footage varies by departments, and can be redacted or witheld by certain departments.
