That is what you do. You take a random sample of no gun footage and have humans skim it.

Yes it costs a lot but it is also a required statistic.

Realistically it shouldn't matter if the shooter knows the pa system is yelling out their location.

A big issue would be it yelling out the location of police.

Have you considered petitioning a 'oil skating' section where folks can slip and slide to their hearts content?

Bc if there was a little space at the side with a sign saying 'see how slippy it is' it would 100% have a bash.

Why is a mech needed so much? Like at all times.

Are failures so common they would shut the place down as nobody could bowl anymore or is it a case that they become hazardous or something?

Jazzy and thanks for the reply. I had no idea that jamming was so common.
