Police don't always investigate crimes to the degree victims expect due to insufficient evidence (no witnesses, CCTV, forensics), limited resources (staffing, funding), case prioritization (focus on serious crimes), or the incident being deemed minor/civil rather than criminal. Failures to investigate can also stem from departmental issues like corruption or misconduct, but often it's a resource/evidence bottleneck where cases go cold without leads, say Reddit users in r/policeuk and Quora users.
Common reasons for individuals not reporting crime include fear of not being believed, insecurity, and fear of getting into trouble. These reasons are most common for not reporting rape. It is commonly assumed that most of the rape cases go unreported; some estimates go up to or above 90%.
The crimes that were most often unrecorded were less serious assaults. These accounted for more than half of unrecorded violent crime. Forces also need to improve their recording of conduct crimes such as harassment, stalking and controlling or coercive behaviour.
A second reason for not reporting crime is that some people may be ashamed of being a victim of crime (e.g., they feel that they may be judged negatively by society or to have in some way precipitated the crime). This is often the case in sexual assault and domestic violence cases.
One of the most important roles of the police is to gather evidence in support of the prosecution of the offender. This process of investigation is typically complex and lengthy; it could take weeks, months or even years to complete an investigation based on the circumstances of an offence.
The police need to have “reasonable grounds” to believe that a crime has been committed and that the person being charged is the one who committed it. This doesn't necessarily mean they need irrefutable proof or “hard evidence” like DNA or a confession at the time of charging.
You cannot be punished for refusing to answer a question. It is a good idea to talk to a lawyer before agreeing to answer questions. In general, only a judge can order you to answer questions.
Results suggest that the decision to report is complex and influenced by multiple factors both within and beyond the criminal justice system including a vulnerable victim, varied types of fear, shame and blame. These findings are discussed in light of the existing literature on rape myths and the ideal victim.
Although many cities rely on official law enforcement data to determine the magnitude, patterns, and prevention strategies for violence, data from the National Crime Victimization Survey conducted by the US Department of Justice indicates that a large number (52.6%) of violent crimes resulting in injury goes unreported ...
It's hard to imagine why an innocent person would confess to a crime they didn't commit, but research shows that false confessions can take place due to law enforcement's use of intimidation, force, coercive tactics, isolation during interrogations, deceptive methods that include lying about evidence, and more.

The hardest cases to win in court generally involve sexual assault (especially against minors), first-degree murder, and complex white-collar crimes, due to intense public emotion, high stakes, lack of physical evidence in sex crimes, and complicated financial details that confuse juries. Cases involving allegations against vulnerable victims, like children, are particularly challenging as jurors' strong feelings can overshadow evidence, while proving insanity or defending clients in federal cases also presents major hurdles.
