EDWARD A. CANIGLIA, PETITIONER v. 
ROBERT F. STROM, ET AL. 

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF 
APPEALS FOR THE FIRST CIRCUIT 

[May 17, 2021] 

CHIEF  JUSTICE  ROBERTS,  with  whom  JUSTICE  BREYER 

joins, concurring. 

Fifteen  years  ago,  this  Court  unanimously  recognized
that  “[t]he  role  of  a  peace  officer  includes  preventing  vio-
lence and restoring order, not simply rendering first aid to 
casualties.”  Brigham  City  v.  Stuart,  547  U. S.  398,  406 
(2006).  A warrant to enter a home is not required, we ex-
plained, when there is a “need to assist persons who are se-
riously injured or threatened with such injury.”  Id., at 403; 
see also Michigan v. Fisher, 558 U. S. 45, 49 (2009) (per cu-
riam) (warrantless entry justified where “there was an ob-
jectively reasonable basis for believing that medical assis-
tance  was  needed,  or  persons  were  in  danger”  (internal
quotation marks omitted)).  Nothing in today’s opinion is to
the contrary, and I join it on that basis.
