As the other respondent says, it depends on your view of accidentally involving the innocent in police activity. In an ideal world, someone wrongly identified would just be questioned, they'd identify that there was an error and there's no physical impact just a brief disruption. That is the approach which genuinely could be beneficial to society. However, I am somewhat concerned that many police officers won't keep the fact that it's fairly likely to be wrong in the forefront of their minds. Combine that with an eagerness amongst some police to start applying "justice" immediately (rough use of handcuffing, pushing to the ground etc), at best treating people like hospital trolleys and at worst inflicting injury, and it's a recipe for escalation and injustice in scenarios involving completely innocent people (and you could argue it shouldn't happen with those who turn out to be guilty too, but that's a distraction!)
