In this country you are innocent until proved guilty.

However, increasing numbers of offences are based solely on the
factual evidence, without any need to prove *intention*. For example
(I don't know the TfL rules, but the railway byelaws state this very
clearly) in a compulsory ticket area one *must* be in possession of a
valid ticket, otherwise it's a byelaw offence. It doesn't matter
whether you paid the fare, nor intended to pay the fare - that byelaw
offence isn't based on intention, it's based on factually not holding
a valid ticket.

You don't have to prove your innocence.

If the accused cannot present a valid ticket, then their mere
*intention* to have paid the fare might not be sufficient. IANAL.
