I think it's quite possible either way. Moving on to another
point, I thought it was clever of the Jackal to disappear by
going to a gay bathhouse and being picked up by a man.
That covered his trail all right, but then it was dumb for him
to let the man go out shopping when he might well have
found that his pickup was wanted for murder, and brought
the police back home with him, which very nearly happened.
Another thing that bothered me was when the policeman
compared the wanted man picture with the 'crippled' Jackal's
picture, and we saw that the faces obviously were the same,
he didn't try to detain him, but sent him on his way, only
telling the inspector about him quite a bit of time later.
Surely the policeman wasn't afraid to try and hold a one-
legged man for questioning.
I suppose in any complicated plot there are going to be
weak points, so the filmmakers try to deflect attention
from the weaknesses by means of the further action.
