What is the test for "deliberate indifference" in a civil case?

"Where actual deliberation is practical, then an officer's 'deliberate indifference' may suffice to shock the conscience." Wilkinson v. Torres, 610 F.3d 546, 554 (9th Cir. 2010). "On the other hand, where a law enforcement officer makes a snap judgment because of an escalating situation, his conduct may only be found to shock the conscience if he acts with a purpose to harm unrelated to legitimate law enforcement objectives." Id. Under the purpose to harm standard, the court looks at the totality of the circumstances to assess whether a jury could reasonably infer any of the officers were acting for purposes other than legitimate law enforcement. Porter, 546 F.3d at 1141.
