2 The suspect claimed that he (watch) TV at the time of the robbery. (Подозреваемый утверждал, что смотрел телевизор во время ограбления. ) - как видим, в таком предложении нужно использовать глагол watch в Past Continuous — was watching.

The suspect claimed that he was watching TV at the time of the robbery

Это значит, что нам нужен инфинитив в форме Continuous, или длительный инфинитив: to be watching
