The laws of the various jursidictions treat this matter differently - and the facts surrounding the alleged "threatening" often play into how law enforcement and the prosecutor view the gravity of the offense.
If the threats are continuous and on-going and accompanied by actions intended to put the victim in fear, they are given great weight. If it only amounts to someone calling you names without further physical actions, not so much.
they could get arrested and depending on the threat they could either be let of with a warning or sent to jail for like a week or two
A speedy trial or court date should happen for a person accused of a crime. It is not legal to drag things out for the accused.
I suppose it would depend on if a crime was involved. If there was no crime, just an accusation that someone was carrying a knife, like in a pocket or purse, and the knife was not brandished as in taking it out and threatening someone, or like used to cut or stab another person, and just someone saying they suspected a knife was being carried.... Then it would just be his or her word against the accused.
They track that person down and they arrest them
Mayella Ewells accused Tom Robinson, the defendant of the case, of raping her. For those of you who don't know what rape is, it's when someone sexually assaults someone else for no apparent reason.Wrong, rape is "an assault by a person involving sexual intercourse with another person without that person's consent".
It depends on the details. A witness is not strictly necessary in all cases. For example, someone doesn't have to see you embezzling, if it can be proven that the money disappeared from account A and showed up in account B (which is your personal account) and you were the only person who could have made that happen.
Unfortunately, not much, except to try to gather the proof you need. Try to avoid the person allegedly threatening you, or try to have someone else around when the threatening person is around you.
Accusing is the present participle of accuse, the act of claiming someone has done something.
Nothing will happen unless the person bullied or someone else tells someone in authority, e.g. a teacher, parent or supervisor, or unless the person bullied challenges the bully.
A veiled threat is when you are threatened without the person actually saying threatening things, but it can be understood what they really mean.
Perpetrator means "the person that did the deed." You are being accused of being the person that did "it."
If the threat is being voiced, in person, to the individual they are threatening, then it is THAT person's responsibility to take action, if any. If you overhear someone planning, or plotting, or threatening to kill someone who is not present - as a good citizen you should bring the information to the attention of law enforcement with as much supporting information as possible. You may be responsible for saving a life. People seldom voice threats like that to absent persons.
accused - yes; convicted - no
