I'm known to make memories, to help preserve the past.
But have you considered a turn to that statement?
One click out of me, and you've shot who's in front of me.
Though used to prevent, I can cause lament.
I'm much deadlier than most weapons, who says I can only shoot people?
The click doesn't just mean a shot, it can also decapitate.
I keep memories of people, after making them a memory.
You can also throw me, but to do so would need lots of hate.
I'm very common, you see. You never know, you're surrounded by me.
I'm able to shoot or behead anyone, but I'm still allowed on a plane.
It's possible that one is looking at you now, ready to click.
Covering your face can save you, but you might be called insane.
Who or what am I?
Look at the title. You might find this riddle funny when you understand where I'm coming from.
