But, how many times have we heard about police being warned and failing to act on said tips? That's not a position they want to be in, either.
Overreacting on a fake call likely means not reacting at all on five other calls. It's a catch-22 situation.
Really? Anyone would be rattled upon opening the door to see an armored-up swat team. It would be hard for them to judge his emotional state, in that situation. Given that they took the tip seriously, I think it wasn't a bad move for them to sit him down in a controlled environment, for questioning. He said they only talked to him for an hour - it's not like they tased him or kept him in jail overnight.
And when he opens the door and shows his hands and clearly has no weapons? What's the need to take him away at that point? "We received an anonymous tip that you had murdered your wife." "WTF? Here's her number, call her right now. You have been tricked and I am willing to sit here while you sort it out."
But the police aren't going to do that, so based on a fake call, this guy gets hauled off to the police station, and wastes at least half a day. For whoever sent the email, that's mission accomplished. They succeeded and will be more likely to do it again. Even an hour wasted is enough to encourage this sort of thing to keep happening. Make the penalties for getting caught much more severe, and stop accepting anonymous calls. That's how you stop fake swatting stuff.
Yes, they should have someone whose job it is to do this follow-up. If it's anything like the situation in US, the problem would be that police in one city might have knowledgeable personnel and resources to do this follow-up, while others wouldn't.
Also, it didn't say 30 police. He said 10 police + other emergency responders. Some of those 10 police cars certainly belonged to the individuals standing in front of his door. Each person there had their own job to do.
He said neighbors said there were a bunch of other police/responders in the vicinity.
And if it turns out to be legit, but investigation burned too much time? "Aw shucks?"
Yes, absolutely you take all of these anonymous calls with skepticism. IMO, it's better to be wrong and/or late and not totally harass innocent people then to show up en force on a prank call. You establish a policy to stop this sort of garbage. The most sensible seems to be, "We can't accept anonymous emails. Here's why." It's literally a no-win situation for the police, and in the modern era, we're quickly approaching the point where the best response is going to be no response.
How often do fake anonymous reports happen? I don't know, only the police departments know. How many anonymous tips do they get in general, real or fake? Again, we have no data. But my feeling is that if there's an apparently urgent call to get people out there on a possible murder, and the person won't give any additional information like their name, it's already suspicious, and an email instead of a phone call may as well be filed in the spam bucket.
This reads like: "Dear police. I heard gunshots at an office near my home. I'm sure the person killed his wife and is now threatening suicide. But I can't be bothered to make a phone call and felt it was easier to create a new email account and send you a message!"
If someone calls the police on a murder, and it's legit, then the police are
already too late. It's better to have a criminal get a head start on escaping than to harass innocents. Being able to say, "We can't respond to every anonymous tip" and explain the reasoning is much better than saying, "We overreacted and wasted time/resources, and possibly caused severe harm to an innocent." Real crimes usually take weeks and even months to sort out, so an extra hour or so of caution isn't the end of the world. If it
is, then things probably already happened regardless.
Personally, if I saw/heard something that warranted me calling the police? Yeah, I'm calling from my cell phone, giving them details, staying on the line as long as needed. And that will be super inconvenient so I'm not going to do it on a whim. "I heard a creak outside the house" or "I saw a guy openly carrying a gun" sorts of stuff won't get me to call the cops. Someone shooting a gun within city limits, or shooting at someone? Yeah, I'm willing to go on the record. I've done this before when I witnessed an accident, wasting hours of my time to try to help out. So I get why people don't want to get involved, but I also understand why it's important to at times be a good citizen and help out.
As long as police allow anonymous reports and show up at a door ready for war, these fake calls are going to be a problem and they're going to continue to happen more and more often. Continuing to show up isn't the solution, in other words. Something else needs to change. The current approach is a clear downward spiral that can never end well for the police departments. It's untenable!
I personally would happily endorse a policy that says, "We can take anonymous tips, but you will not get and should not expect a rapid response of any form because that has led to problems in the past. If something is urgent and needs an immediate response, you will have to give up your anonymity. This will help us to avoid fake responses and we find that is better than having a system that's ripe for abuse."
