meaning of a weird punctuation
Does the sentence after the colon mean:
1. unwitting bystanders who haven’t read the script and some tourists who find themselves literally frozen out.
or
2. unwitting bystanders who haven’t read the script who are some tourists that find themselves literally frozen out.
Context:
In amongst this immobile mob, the odd ripple of activity: unwitting bystanders who haven’t read the script, some tourists perhaps – others definitely pigeons – who find themselves literally frozen out.
