Next it will be smart phones which can do many of the things these devices can do when rooted the right model.
Not hard to make a walking stick that can do wireless shenanigans, that gets overlooked by all.

If your walking stick looks like it will be used as a weapon then you can safely assume you’ll have it removed upon entry.
Events like these will have disclaimers like “admittance is subject to the discretion of our security staff”.
The point of the list of prohibited items is to make it easier for attendees to know the kinds of items theyre allowed to bring. What it isn’t, is an exhaustive list of anything that could be used for bad intentions.
