the cost isn't necessarily that high. people have been installing privately owned cameras, such as doorbell cams or ones for businesses, at incresing rates for the past while. many of the doorbell camera or general internet of things camera companies will turn over footage stored on their servers without consent from the cameras' owners at no cost, and as for the businesses they can be easily strong armed into turning their recordings over by the implication that law enforcement will be less responsive to the uncooperative and even then they can just run thru a subpoena in a matter of hours since a sacred cow richfag was the victim.  so while anon is over stating things, there probably is a decent amount of recording footage available to the various law enforcement types who will be involved in this.
