maraming pagkakamali ang pulis dito in my point of view
1. evidence was mishandled, as evident in some videos
2. the police didn't secured the crime scene as soon as possible (not counting the cleanup since this was beyond the police's control)
3. the miranda rights was not read when the helpers and relatives were taken.
4. warrantless arrest are not allowed unless the perpetrators are caught in the act.
5. the arrest made on the relatives in the hospital was done excessively. the relatives were already begging for pam not to be taken at that time for humanitarian reasons. the police ignored the pleas. there are videos proving that.
6. the early press cons of the police (parang masyadong pang maaga para maglabas pa sila ng detalye sa pangyayari)
sa tingin ko lng naman to,kung may mali dito,pakipoint out na lang.
