While I was watching Toy story3, i got the sentence below.
1. Any prisoner misses roll call, spends the night in the box.
2. Any prisoner talks back, spends the night in the box.
I think the orginal sentence seems 'Any prisoner who misses roll call spends the night in the box'. What I wonder is whether #1 and #2 also are possible. I have known objective relative pronoun can be omitted, but subjective relative pronoun usually can not be. But in the movie there is, so I am confused.
Many thanks in advance!
The omission of subject relatives occurs occasionally in informal speech.
