Not only can “power” users be used, can any other species invent a laser pointer or dagger that can retract the laser blade? Well, there is a laser type weapon called the energy sword. It is made of plasma-almost their version of lightsaber (saber is just a sword). Variants include blood blade, plundered silver, and green variants.
There are other content in the game. So yes, in the novel, anyone can make an energy blade with a retractable blade. In real life…not so many…Does the scene really exist in terms of security like a spy movie? Laser sensors are really safe, check if someone has destroyed them? Of course; you can buy it from Amazon.
Of course, they are invisible, not bright red. Do they exist like in the movie “Framed”, where Catherine Zeta Jones (or any star) moves very carefully and poses interesting poses to attract the audience’s viewing pleasure? Frankly speaking, the designers of security systems are usually not idiots. If you are not using a laser field crisscrossing the floor about a foot apart, but a row of vertical lasers 4 inches from the floor to the ceiling, there is no way for the head to pass through them.
Therefore, human thieves cannot defeat them by posing or flipping (and you also place them on the edge of the room to make it more difficult for people to use their laser pointers). Oh, all laser safety systems are invisible to the human eye, because of course they are.
You can also use passive infrared sensors to back them up so passing them will trigger the layer. Visible laser grids with random patterns are used for movies, TV shows and escape games, not for any serious security. Is there a computer game/Hollywood version where a more powerful green laser pointer is sufficient to cut steel? That would be a ridiculous waste of electricity and powerful lasers.
