Twitter itself is largely a waste of time, that is a conclusion I have come to after spending quite some time on it this year.
If the Police are using it whilst on duty, it smacks of unprofessionalism.
Now, more controversially, I am very much against breathalysing people in the morning.
I have known people (myself included), who leave the car overnight for fear of being over the limit.
That is a very responsible attitude take.
But, it has been known quite often, for people to FAIL the breath test the next day, despite going to great lengths to not drink and drive the night before.
Being hungover, and being intoxicated are two very different things, and I think it is a very unfair outcome if anyone gets a ban for that.
