If that's the criteria for a terrorist, then I think a lot of Boy Scout and Girl Scout leaders just got put on the watch list. What a waste of tax dollars.
I think its a little more subtle than that, for example if you own 100+ camping stoves, fixed bladed knifes, field rations, flashlights or SAKs or whatever, the state security intelligence logic (

) is that no-one would ever need that many and logically you must be secretly acting as a distributed quartermaster for an insurgency group or even worse, where one person within the group holds one individual item for that networked group.
