Evidence, Media, and Witness Testimony in Criminal Cases
Physical evidence like DNA and blood samples pack the biggest punch in court because they're scientifically proven and hard to argue against. However, contamination during investigation can completely mess up a case and potentially lead to wrongful convictions.
The burden of proof sits squarely on the prosecution's shoulders - they must prove guilt whilst the defence can only challenge their claims. This gives prosecutors a major advantage since they control most of the evidence presented to the jury.
Media coverage can absolutely destroy the "innocent until proven guilty" principle. Take the 2011 London riots after Mark Duggan's death - media reports about his alleged criminal background sparked moral panic and influenced both public opinion and harsher sentencing for riot-related crimes.
Key Point: The media's portrayal of suspects often creates public pressure that can influence trial outcomes, even when initial reports prove inaccurate.
Eyewitness testimony might seem reliable, but it's surprisingly flaky. Memory fades over time, stress affects recall, and even seeing similar photos can alter someone's recollection. The Ronald Cotton case shows how confidently wrong witnesses can be - Jennifer Thompson was "certain" of his identity, yet DNA evidence later proved his innocence after 10 years in prison.

Expert Witnesses and Political Influence
Expert witnesses carry serious weight because juries trust their specialist knowledge and credentials. They help explain complex evidence that ordinary people might not understand, making their testimony incredibly influential in reaching verdicts.
The Sally Clark case perfectly demonstrates how expert testimony can go horribly wrong. Professor Roy Meadow claimed the odds of both her children dying from SIDS were 1 in 73 million - completely flawed statistics that helped convict an innocent mother. She served three years before the conviction was overturned, but the damage was done.
Political pressure shapes criminal justice through Parliament's law-making power and influence over sentencing guidelines. Politicians can effectively pressure judges to impose harsher sentences, especially during public outcry over particular types of crimes.
Key Point: The Arms to Iraq scandal shows how political considerations can influence prosecution decisions - sometimes cases don't proceed because they'd embarrass the government.
The Dangerous Dogs Act 1991 emerged from media-driven moral panic about certain dog breeds. This demonstrates how political responses to public fear can create sweeping legislation that affects thousands of people based on isolated incidents rather than solid evidence.

Judicial and Legal Team Influences
Judges wield enormous power in criminal trials through their ability to interpret law, advise juries, and determine sentences. However, they're supposed to remain neutral - when they cross this line, it can invalidate entire convictions.
The R v Wang case from 2002 shows what happens when judges overstep their boundaries. Wang carried religious weapons and was found guilty after the judge directed the jury's verdict. The conviction was later declared invalid because judges cannot influence jury decisions - that's the jury's job alone.
Barristers and legal teams can influence outcomes in unexpected ways, including through their physical appearance and charisma. Research suggests attractive defendants and lawyers may receive more favourable treatment, though this shouldn't affect justice.
Key Point: The George Steen fraud case shows how jury members can become inappropriately interested in attractive barristers, potentially affecting their verdict decisions.
The champagne incident in Steen's trial - where a jury member sent the prosecution barrister her phone number - demonstrates how personal attraction can compromise the entire judicial process. Steen used this incident to appeal his sentence, arguing the jury foreman's interest in the prosecutor may have influenced the guilty verdict.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
