them's them

When an old lady is robbed of her handbag in the middle of a crowded railway station, the police officer she ran to for help, asked her if she could identify the two youths in a lineup.

As she catches sight of two young thugs leaping over the turnstile gate but a hundred years away. In a burst of frustration, the old lady points at the turnstile and screams:

"Them's them!"

What should she have said?
