Security - Playing In the Park (Spoiler)
After the boy is recovered and they are playing ball in the park, why is there no security? Tom could afford to have them surrounded by private security.
Likewise, when they go back to the apartment, there is no security, just a maid.
After such a traumatic incident, Tom would naturally have security downstairs, outside and inside the apartment for at least a few months.
When Tom wrote the cheque for Shaker, he would have one or two armed guys protecting him and the boy.
It makes no sense to pretend that nothing had happened and go back to how things were before, particularly as Tom could afford as many security guards as he needed.
