[[Yep. They can and if you followed the Trayvon martin case you’ve seen how that can go.]]
Followed it - George was fully justified in shooting Trayvon- But to the point- citizen’;s arrests happen without incident as well- just as police arrest happen without incidence, and some not so much- it’s a gamble for sure- but when good people do nothing, evil prevails- thankfully we have citizens willing to take the risks, and help protect the public when needed-
Ummm ... The justification for lethal force against Martin was from other factors.
One mans citizens arrest is another’s unlawful imprisonment.
