1. I saw him questioned by the police.
2. I saw him be questioned by the police.
3. I saw him to be questioned by the police.
4. I saw him being questioned by the police.
Which sentences above are correct & which are wrong? Could you tell me the difference in meaning between sentence 3 and sentence 4?
Your help is cordially appreciated.
Among 1, 2, 3, to me 1 is the most acceptable. 'see' as a verb has complex transitive complementation, SVOC, where C = inf. clause whose 'to be' is wiped away.
I am not convinced that #3 is incorrect grammar. We just do not use 'to', although it is still there.
