The law abrogates longstanding common law duties. IMO....it was the legislatures intent to make people more protected in situations where they may be subject to random violence. As written, and as applied in some cases, the effects of this law have not been confined to such circumstances. IMO, when the two people are acquaintances, and when other evidence goes to factors like initial aggressor and the like...the law needs to do more than remain silent...and as such should be amended. There was a body of case law that addressed this type of issue...this provision change that...and it is unclear how this should be applied in certain circumstances ... many people (including law makers in Florida) do not agree that the person seeking immunity under this statute should be unquestionably protected by irrefutable presumptions in all circumstances...most notably when evidence can prove up who was the initial aggressor...but also when it is a factual question for the jury or when other circumstances such as relationship and the like are present.
