Well, with all due respect - the problem in INDIA & especially MUMBAI is manifold...
Monitoring is IMPOSSIBLE due to vast Population. Period
Corruption is Rampant & Courage is ... well ...very very hard to find & often mocked at.
Therefore, the legal authorities & the powers that be - are at best often helpless.
We cannot take matters into our hands entirely. But we the Citizens, the Youth can definitely do something.
1. FEAR NOT, PANIC NOT.
2. AWARENESS is the Key: talk openly about it - dont avoid it, dont ignore it.
3. Each Individual can make a difference... together it will all count.
You take care of your home, your building, your street, your area. Collectively & Consequently the city remains Area, City & Country WILL be safe.
The US have a concept of HOME GUARDS.
Suppose, individuals , who volunteer, are TRAINED in certain basic things like COMBAT & Avoiding Panic - by say the Police or the Army & they are endowed with certain responsibilities & previliges.
They may not be part of the judiciary system. They may not be equivalent to a police officer. They may pertain only to certain demarcated area - or may act as extra alert & extra prepared individuals WHEREVER they are in the city.
Their Identities should be kept as hidden & secret as possible - so people dont keep approaching them. they will come to help as & when needed. They may or may not be given ARMS licences. Their Backgrounds & Identities should be thoroughly checked & verified before they are inducted into training. They should not be given special uniforms. Just a inconspicuos badge or ID. The point is people around should not KNOW who they are & what they represent. Silent informers, guards, workers who shall play a vital role in Averting, or Managing such - DISASTROUS ACTS.
