The officer is very suspicious of you so you will have to corroborate your story by showing him your detective badge. As you reach inside your jacket he draws his gun and says "Nice try, but you'll have to do better than that to pull a gun on me." He handcuffs you despite you protesting your innocence and he wrestles you into the back of the police car.

It will take a few days to sort this little mess out, but by then it will be too late for you to stop the robbery taking place, and you may also have put the security of your employers at risk by attracting unnecessary and unfavourable attention.

You have failed miserably in your mission.
