This reminds me of a question I had to answer on an exam in what was then called Air Police School at Lackland AFB, at San Antonio. This was a police academy that I attended after completing basic training.
As I recall, it lasted eight weeks.
The question was, where does the air policeman park his own vehicle after stopping an offender's car?
In front of the offender?
Behind the offender?
To the rear of the offender?
Beside the offender?
I wasn't sure whether it was behind or to the rear. I chose the latter because it seemed more formal and got the correct answer. BTW, I passed out as second man in my class of about 150 and got a special citation for academic achievement. I still have that and on days when I feel a little low, I get it out and read it. That and having published about 5,000 magazine and newspaper articles and produced two brilliant children are my primary claims to fame.
Of course, I'm a member here. That's sort of impressive, I hope. I try to be helpful.
