The museum has four VCRs under the security screens. The first three VCRs are empty, but the fourth had a tape in it. You view the tape and fast-forward all the way to the end - the tape is blank. When you ask Bill Leitner about it, he said he turned it off to change the tape at the beginning of his shift and forgot to turn it back on.

Now that you’ve seen the video, any thoughts?

Based on the information provided, it seems that there may not be any useful footage on the tape since it was blank. It also appears that Bill Leitner may have forgotten to turn on the VCR after changing the tape, which could have resulted in the lack of footage. It may be worth checking with other staff members to see if anyone else had access to the VCR or if there were any other incidents that could have affected the tape. Additionally, it may be a good idea to review the museum's security procedures and ensure that all staff members are properly trained on how to operate the security equipment.
