He reassured members of the public that their requests for help would be dealt with. "Shopkeepers and the general public can be reassured that the police will respond with urgency to situations where assistance is needed. Ring 111, observe what is happening and let police deal with these situations."
Sensible Sentencing Trust spokesman Garth McVicar said store keepers were often placed in a position where they had to make on-the-spot decisions and didn't have time for police to arrive.
The law about how much force was "reasonable" was vague and made it difficult for shop owners who were trying to defend themselves in potentially dangerous situations.
The key issue here is hesitation. If we posit a binary solution set:
1 - We do not apply sufficient force, the attacker is capable of retaliation, the victim is further injured, or;
2 - We apply too much force, the attacked is incapacitated,
we can see that logic favours applying too much force. We, as the self-defender, cannot be sure how much is sufficient. We do not know the abilities of our opponent. We do not know whether he is hopped up on drugs. Usually, we have no ability to RESTRAIN him, but rather must use force in a way that incapacitates (of course it'd be unreasonable to use force if we had handcuffs or something, i'm not advocating a free for all)
The final issue - I'm sure someone will bring it up - is what do we do if the assailant begins to flee? Well, that raises 2 more issues
- will the assailant return with allies before the police arrives?
- will the police be able to track the assailant if he gets away?
Again, both of these issues suggest the use of additional force.
