Art and his son Ben were hunting on property owned by Carl without the latter’s permission.  Carl cherished the deer and other animals on his land and considered them to his pets.  The sound of gunfire awakened Carl who rushed to the scene of the sound emanating from Art’s rifle. Carl himself then fired two shots from his own gun in the direction of Art in order to scare the intruder from his property and to protect his beloved deer.   Unknown to Carl, Ben was standing near his father behind a tree when Carl’s shot struck Ben in the head, killing him instantly. Concerned that he was under attack, Art returned fire against Carl.  One of the shots from Art’s rifle struck Carl in the shoulder and disabled him.  All of the commotion associated with the ongoing gunfire led Doug, a farmhand who worked for Carl, to rush to the scene with his own rifle.  As Carl came into his view, he saw Art running towards his now disarmed and bleeding boss.  Doug then took aim at Art and fired two shots directly at his legs.  One of the shots struck Art and he fell to the ground.  Doug then approached Art, kicked his rifle out of reach and called the local Sheriff for assistance. Discuss all legal issues concerning (1) Carl’s criminal responsibility for the death of Ben; (2) Any defenses Carl might raise concerning his use of force; (3) Any defenses Art might raise concerning his use of force against Carl; & (4) any defenses Doug might raise for his use of force against Art. With regard to calls (3) and (4) discuss both majority and minority approaches to the issue where applicable.   Assume the common law applies in this jurisdiction.   

Which situation is an appropriate indication for indwelling catheter insertion?

Three recent college graduates, Art, Ben and Carl, were playing cards one night.  They became engaged in a discussion about how bleak their future job prospects were because of Artificial Intelligence and the current corporate downsizing.  Art expressed the view that they should strike back at those who were robbing them of their future.  He proposed that they should take control of a nearby data center and threaten to blow it up if the corporate managers didn’t deposit $1million in a designated bank account within four hours.  While Ben expressed some initial reservations, Carl pointed out that split three ways, this would be more than enough money to pay off their student debt.  So. the three of them agreed to the plan.  Ben purchased explosives and Carl obtained a firearm in case things got out of hand. On the day of the caper, the three young men arrived at the data center and were met by a receptionist.  Carl, removed the gun from his jacket pocket, pointed it at the receptionist and told her to send the agreed upon message to the corporate “big wigs”. Frightened and weeping, she complied and conveyed the threat to the corporate office.  However, to their great surprise, the corporate office sent a return e-mail which read, “Go ahead.  That’s why we have insurance.”  As a matter of principle, the three men agreed to carry out their threat.  So, Art lit the fuse on several of the explosives and was once again surprised to find that Ben had mistakenly purchased fireworks.  Although the fireworks obviously did not destroy the data center they did set fire to the facility, which was saved only by the diligence of the local fire department.  The three men were apprehended as they sought to escape the scene. Discuss all legal issues regarding: (1) Art’s proposal; (2) the agreement to the plan; (3) the criminal responsibility of the three friends for the events which took place at the data center.    Assume that the common law applies in this jurisdiction.  However, with respect to the data center fire apply modern statutory law.
