During
Miranda vs. Arizona, the difficulty of using police interrogation recording
equipment came into light. The case addressed that an interrogation
must be isolated to obtain accurate information, but this is made difficult
with recording devices present.
Since group interrogations have proven ineffectual, most agencies prefer
to question single persons. However, police interrogation recording
equipment must be hidden for the suspect/witness to give unbiased information.
Otherwise, knowledge of recording devices may hinder/alter their testimony.
There are several snags to using police interrogation recording equipment.
For example, interviews often run longer than a standard tape in a video
recorder. Many agencies don’t even have the funding for adequate
audio/video technology.
