The person did not accept being in custody. That's why the person resisted. You don't resist if you come willingly .
If you don't come willingly, you will be forced. People that are in prison that want to leave have to stay against their will like any slave that has a will to not be enslaved.
You can repaint this picture as a willing party but then the issue is, why do we have to keep handcuffs on like shackles, locked behind walls and gates?
An unwilling person doesn't want to stay imprisoned and people have tried to escape TO FREEDOM. They're not free.
So if you admit they're not free, are they just as not as free as a slave?
Gotta keep the consistency here. You don't realize you're truly supporting freedom taking away from some people which is good.
