Police. What unit shell I go in?

You are talking nonsense. They will not take you with such a poor grasp of what is involved. Do you really think that you can choose what unit to go in. You join the police and spend years on the beat, then you apply for different units. Sorry but you will need to grow up a bit before you try to recruit.

You are clearly far too immature yet and have no grasp of what the police do. Hopefully, by the time you are old enough you'll have gained a better understanding.

If and when you are accepted, after successfully completing training you will spend at least two years as an ordinary constable before being eligible to be considered for anything else.

I think you should concentrate on your English first, the last thing a police officer needs to do is fill in loads of statements, get to court only to find that the bad guy has got away due to a lack of attention to detail.

Which ever unit you work in, you will enjoy yourself, generally you are expected to be a standard bobby for a couple of years and then see what opportunities open up.

First get accepted, complete the training and do the required probationary period.

The see how much fun you think it is and see what is offered.

At the moment your perception of what is actually involved is a little warped.

Fun? I think you've been watching too much TV

What makes you think you will have a choice - you won't

you do not sound to be a good candidate for law enforcement
