Sure, two cameras failing at the same time right before he incident seems very suspicious. But is that the case? Seems more likely both cameras were broken and had been for a long time and were never fixed. How many other cameras in the facility were broken? If cameras are broken, how would you ever learn that they are broken? Perhaps it would require an important event like a suicide to occur so that you would need to review the tapes and discover the broken cameras.
