I'd just point out a few things for your added consideration.
We have the provision in this citizen's arrest that it's only when you're not able to engage the police to make the arrests, so I don't think we would be in the scenario of somebody waiting around to get their buddies together to go and effect an arrest, because if that were the circumstance, then clearly that person could have made an attempt to engage the police to arrest the person.
The extension of time in these amendments is designed for the situation in which the person can't effect the arrest at that very moment because the person runs off or whatever, and then they encounter them at some other opportunity and they can't get the police to effect the arrest.
Therefore, we would prefer that the wording be left “reasonable”. The courts will interpret that appropriately, and if we added in “at the first reasonable opportunity”, the discussion could be around when was the first reasonable opportunity rather than whether the person's action was reasonable in effecting the citizen's arrest at that time, looking at all the circumstances and whether they had any ability to engage the police and so on.
When you're changing the law, you look at a variety of considerations, and in this one, moving from the precise idea of finding someone committing an offense and arresting them at that time to some extension.... Obviously we don't want it to be in perpetuity or in an unreasonable timeframe, but the thinking is that by saying “reasonable”, there is sufficient guidance to the courts. The circumstances will govern it, as many members have noted, depending on where you are and what the case is.
