Here is a list of things that the FBI says make you a possible terrorist:
if you pay cash for small purchases like a cup of coffee, or for large purchases
using encrypted files
shaving off your beard
SCUBA diving without certification card, or SCUBA training to get a certification card, being a SCUBA diver without a logbook, diving using “rebreathers”, use dive equipment for extended dive times or deep dives
taking pictures with a cell phone, having more than one cell phone, buying more than one disposible cell phone, not activating a prepaid phone at the time of purchase
At work: likes to work alone or unsupervised, and if at work, is willing to do tasks that no one else wants to do
people who are overdressed, underdressed, or are dressing to blend in
playing paintball on your own property
buying waterproof matches, MREs, or flashlights
absence from work for charity work
study of fields that can be used for terrorism like chemistry, gunsmithing, SCUBA training, rappelling, marksmanship, etc.
When renting a vehicle, inquiring about its fuel capacity
receiving a large number package deliveries
having weapons on your property, or buying bulk ammunition
refusing to allow landlord to enter rental property on demand, or changing locks without landlord permission
having offensive tattoos, or asking to have offensive tattoos concealed, covered, or altered
owning remote controlled model aircraft
use of model rocket engines and igniters
buying firearms and ammo outside of hunting season
requesting hotel room in specific location or floor
arrive at hotel with too little or too much luggage
persons mumbling to themselves
excessive sweating
This list covers so many activities that it is useless. If you read the list, everyone is a possible terrorist, because if we just focus on Muslim males between the ages of 16 and 35, the terrorists will know this and exploit it. Except looking harder at Muslims is profiling, and we can’t do that, that would be insensitive and discriminatory, thus ensuring that the terrorists don’t need to disguise themselves as non-Musilms.
