There is no prospect of a caution I'm afraid.
This is an offensive weapon and a sword is an offensive weapon per se.
A caution is incredibly unlikely and just not on the spectrum. It would be like receiving a caution for an offence like rape which does happen but only in the rarest of circumstances.
A charge is inevitable unless, of course, he has a positive defence.
If he is convicted either upon plea or upon verdict then he will have a criminal record and it will affect travel and may affect employment. In fairness, offensive weapon does have an impact but only upon certain occupations.
At court the disposal depends on the circumstances and his age.
I personally wouldn't mitigate on the basis of autism. I'm not sure Magistrates really believe in it at all and also there is an argument that a person with difficulties is more dangerous with a weapon than a person who does not have those problems. Some people disagree with me but that has certainly been my experience.
If you give me more information about this came about I might be able to tell you more.
Can I clarify anything for you?
Well, that is a very good deal. I would take it.
A caution isn't a criminal conviction but it is a record.
Yes, it will affect travel and may affect employment depending on what he wants to do. It doesn't change much from a conviction except that you don't have the punishment to contend with.
Not sure if that uploaded?
