On this page of the guide, you will find the only effective method of overpowering the cop in Twelve Seconds by electrocuting him and tying him up.
Our hero can not compete in any way with the stranger. Using tools, including a knife, will not be effective. There's only one way to knock the cop to the ground - electricity.
To put down the burglar, first put your wife to sleep with sleeping pills (chapter: Sleeping pills - how to use?). Now go to the bedroom and turn the light on and off. A broken switch electrocutes only the second time someone turns on the light. The burglar will do this when it's dark and won't pay attention to anything else.
Hide in the closet, closing the door behind you, and wait. Don't come out of the closet until the burglar fall on the floor. If this is not the first loop, the time waiting in the closet will be fast forward until the arrival of a police officer.
You can search and tie him with your bands - this method is not very effective because the burglar will quickly wake up and free himself.
This is where we end the topic of overpowering the cop to avoid excessive spoilers - if you don't know how to deal with the further game, check out the next page of the guide Bumblebee's number - how to get? or check one of the endings.
