Moreover, defendant's requests and the administrative decisions supporting them were narrowly tailored to achieve the legitimate objectives of ensuring defendant's safety and maintaining institutional security. See Pratt, 65 F. 3d at 806 (defendant's challenged conduct will overcome a retaliation claim if it advanced a legitimate correctional goal that was tailored narrowly enough to achieve the goal); see also Turner v.
