How Police Build a Strong Evidence-Based Case for Robbery Allegations

Receiving a call from WA Police alleging you have committed a robbery is one of those events that will certainly change your week, if not the whole year. You were busy living your own life one minute, and in the next minute, you try to figure out what “circumstances of aggravation” actually mean. If you’re searching for answers right now, a robbery lawyer in Perth can walk you through this.

This blog extensively deals with what goes into the process of how the police build a robbery case.

What Makes Robbery Cases Be Taken So Seriously in WA

Robbery occupies an interesting legal area in Western Australia; it’s neither theft nor violence, but a little bit of each at once. These circumstances make the prosecution of these cases quite difficult indeed because:

  • The basic charge of robbery is punishable by up to 14 years’ imprisonment.
  • If the crime is committed under aggravated circumstances, it is punishable by up to 20 years.
  • Armed robbery and robbery committed by means of pretending to be armed with an offensive or dangerous weapon result in a maximum life imprisonment sentence.

The WA Police have documented about 1,635 cases of robbery offences in the state each year. At the same time, victim surveys show that there are about 67,500 people in Australia who fall victim to a robbery-like crime every year, and only about six out of ten report it to the police.

What Police Actually Collect First

It is highly unlikely that robbery investigations will begin with a confession. It begins with fragments, and police officers put those fragments together to make a whole case for the District Court.

  • The original complaint, what was reported by the victim, when, and to whom.
  • Scene evidence, such as fingerprints, shoe prints, dropped objects and signs of forced entry.
  • Footage of CCTV cameras at the scene, near the scene, from traffic, even doorbell cameras on neighbouring houses.

None of these is treated as absolute. People’s memories under stress are fallible, and many initial “certainties” from witnesses become much less certain when put under scrutiny during cross-examination.

Witness Statements and CCTV Footage: The Mainstay of Most Cases

If you have received a call from the police, it could be due to footage or a witness statement. Here is where professional advice from a criminal lawyer in Perth WA, can make all the difference because, in most cases, the quality of the footage and the reliability of the witness are weak points.

Police would usually:

  • Get footage from different angles and different timestamps, and not just one source.
  • Separately interview witnesses and check their consistency.
  • Ask victims to point out the person guilty in a series of photographs or an identity parade.

Inconsistencies between witness statements and footage are usual, and that’s the first strand to be pulled on in the defence.

Digital Trails: How Phones and Bank Records Seal a Case

Modern cases of robbery involve the use of information that is not considered by many people. Information such as the ping of the phone tower, GPS coordinates, bank transactions, and even ridesharing information can pinpoint the position of an individual near the crime scene or otherwise.

Police commonly request:

  • Data from the mobile phone towers to trace out movements at the time of the crime.
  • Bank transactions related to stolen goods.
  • Posts on social media sites that mention money, goods, or a particular time frame.

This digital aspect is very effective but also often misunderstood. Being “close” to something does not mean taking part in committing a crime, and a competent legal team knows how to test that distinction properly.

How Early Lawyers Help Shape the Outcome

The police prepare their case from the time the event is reported, not the time that the criminal charges are filed. Each day without receiving proper legal counsel is one day during which the prosecution prepares its case, and the accused remains silent.

Hiring a lawyer for shoplifting early on will allow for the following:

  • Proper review of the CCTV and witness evidence before it becomes part of a brief.
  • Errors that have occurred in the gathering of the evidence.
  • Negotiations in some cases, even before the case becomes official.
  • An honest assessment of the situation you are facing.

Conclusion

The longer the police have to accumulate and analyse all available evidence, CCTV footage, phone evidence and witness statements, the more convincing and difficult it will be to rebut. This is why consultation with a reliable theft crime lawyer in Perth is of such vital importance in such cases, and why it is important to consult with one as soon as possible.

The experts in these domains have analysed similar evidence many times and have developed a realistic view of how a particular case will unfold.
