The use of drones in law enforcement in India has significantly improved surveillance capabilities. Here are some points regarding the use of drones in monitoring roadblocks and their impact on law enforcement:

• Firstly, drones enable law enforcement agencies to monitor dangerous roads and checkpoints remotely, reducing the risk to officers.
• The drones' ability to capture live footage also helps police to gather detailed visual evidence, enhancing forensic investigations and potentially improving outcomes in court cases.
• Furthermore, drones can be used to cover large swaths of terrain quickly, helping law enforcement to create effective barrier plans and respond proactively to any unexpected issues.
• The technology also enables police to monitor areas that are difficult to access, for example, remote rural roads which have previously been vulnerable to criminal activity.
• Using drones as a policing tool not only improves public safety but also reduces costs associated with traditional methods of surveillance, such as manned patrols or helicopters.

Overall, the use of drones has helped to transform law enforcement in India, enabling more effective and efficient policing of roadblocks and other high-risk areas.
