Several excepts. There is MUCH more at the link -- go read the whole thing, well worth your time.
The Client
The client does not have to be a clean-cut pillar of the community who carries a lawfully-owned firearm in order to qualify for self-defense, but it is helpful.
...
Ideally, the client will also have some formal training in the use of deadly force which will allow the client’s teacher to testify about the client’s training in order to show that the client’s actions were subjectively reasonable.
...
When the client is under life-threatening stress, he or she cannot calmly engage in a conscious, deliberative, and analytical reasoning process. Instead, the client will react automatically, ... Simple habits are easier to follow than complex responses ... This automatic reaction is one reason why it is important to find out whether the client has had any self-defense training and talk to the client’s trainer.
...
Some authors suggest that the stress-triggered hormones affect the client’s memory, and that a client can provide more accurate statements if he or she waits 24 hours and gets some sleep before giving a formal statement.5 The attorney should ask about the investigating department’s officer-involved shooting policy. If, like New York City, it requires that officers be given 24 hours and bed rest before giving a statement, and the client was pressured to give a statement sooner, the attorney may have good fodder for cross-examination.
...
If a medical expert is giving an opinion about entry and exit wounds or how the aggressor was standing based on the wound channel, the attorney needs to carefully explore the basis for the expert’s opinion. Be skeptical about testimony by emergency room doctors. A 1994 study showed that hospital trauma specialists misinterpreted the number of gunshot wounds and mis-identified entry and exit wounds in 52.2 percent of cases studied (i.e., slightly worse than if they had guessed randomly).6
...
Another set of troublesome facts involves a client who seemingly used excessive force by shooting an aggressor after the aggressor fell, began to run, or turned away. Explaining these facts to the jury involves explaining reaction time
...
Human beings are, fortunately, hard to kill instantly. ... Stopping an aggressor may take one blow or several blows. And the client will not have time during the midst of a chaotic struggle to stop after each blow or shot to evaluate its effects.
...
Some courts imply that firing multiple shots is evidence of intent to kill or is a sign of excessive force, which disqualifies the defendant from self-defense. Look carefully at police use-of-force cases. ...
An attorney will find that in many cases, police officers have to fire many bullets before the suspect is stopped ... Police officers also fire many more shots than actually hit — 42 to 80 percent of shots fired miss at typical ranges of zero to 10 feet.11 Police officers cannot be sure, until the aggressor falls down or flees, whether they have even hit the aggressor. The same problem confronts clients who are not law enforcement officers.
...
Wounds in the Back
This is a very troubling fact for many juries...
...
Firearms and Unarmed Aggressors
As noted above, if the client used a deadly weapon, especially a firearm, to defend himself against an unarmed attack, the attorney will have a difficult time convincing the jury that the client acted in self-defense.
... As the U.S. Court of Appeals for the Third Circuit noted: “A reasonable officer would not be expected to take the risk of being assaulted by a fleeing man who was so close that he could grapple with him and seize the gun." ... Similar logic should apply to citizens as well.
...
‘Killer’ Bullets and Hair-Triggers
...The client will be in the strongest position if he or she used a firearm and ammunition similar to ...
...
The right of self-defense is most endangered when it is inadequately defended in cases where the client is unsympathetic, has a long criminal record, or is a gang member or narcotics dealer who defended himself in a quarrel with a rival gang or dealer. Here, courts and police will be most willing to restrict the right of self-defense in an effort to curb urban violence. The decisions in these cases have a long reach and often unforeseen consequences. ... Ultimately, the decisions in these cases affect every citizen in this country.
