Nice answer , if we go by that reasoning again it would mean that a stone could be classified as a weapon too , so it should be difficult to classify telekinesis as a weapon
All depends on circumstance and intention.
I may be prevented from taking a bottle into a football match as it is viewed as a potential weapon/missile.
I'm unlikely to have a bottle taken away from me in a different setting.
That's why laws are almost always phrased in a nice, general way that can be interpreted just about however the enforcer wants it to be.

Rather like Scotland's wonderful offence of Breach of the Peace.
To fall afoul of this law, you will have been doing something that causes (or could cause) alarm or distress to the public.
Means that it can be used for pretty much anything and is invoked whenever someone is acting in a way the police don't like, but isn't actually breaking any specific law.
Football fans are more likely to be done for Breach of the Peace than anything else, because most of the time they aren't really doing anything wrong.
